Best eSIM for Costa Rica 2026: Tested in San José, Manuel Antonio & Tamarindo
We tested 6 eSIM providers across Costa Rica — San José, Manuel Antonio, Tamarindo, La Fortuna, and Monteverde. Speed tests, pricing, and top picks for travelers and nomads.
The best eSIM for Costa Rica is Airalo . After testing eSIM providers across San José, Manuel Antonio, Tamarindo, La Fortuna, Monteverde, and Puerto Viejo over 3 weeks, Airalo delivered the widest plan selection, reliable Kölbi network connectivity, and the marketplace flexibility to compare operators before buying — critical in a country where the “right” carrier changes significantly depending on whether you’re beachside in Tamarindo or hiking in a cloud forest. For best value per GB, Saily connects to the Kölbi network, averaging 45-55 Mbps in San José and 30-40 Mbps in tourist areas — at the lowest per-GB pricing we found.
For ultra-cheap daily plans, Trip.com offers Costa Rica eSIMs from just $0.39/day with daily data resets. For unlimited data, Holafly ‘s Costa Rica plan is the top pick for remote workers and heavy streamers — just note that tethering is restricted. For first-time eSIM users, Nomad eSIM ‘s free trial lets you test before committing.
Here’s every provider we tested, with real speed data from 120+ tests across 6 Costa Rican destinations, full pricing breakdowns, and clear recommendations for every type of traveler.

How We Tested eSIMs in Costa Rica
We didn’t rely on spec sheets or marketing claims. Over 3 weeks in Costa Rica (February–March 2026), we activated each provider and put them through real travel conditions — airport shuttles, national park entrances, beachside coworking spaces, jungle lodges, and fast-food joints in San José.
Destinations tested: San José (Escazú, Miraflores, La Sabana, downtown), Manuel Antonio (town center, park entrance, Biesanz Beach), Tamarindo (main strip, surf break, beach road), La Fortuna and Arenal (town center, volcano viewpoints, hot springs), Monteverde (Santa Elena town, cloud forest reserve entrance), and Puerto Viejo de Talamanca (town center, Cahuita).
Testing methodology:
- 120+ speed tests using Ookla Speedtest and Fast.com at different times of day (7am, noon, 6pm, 10pm)
- Real-world performance on video calls (Zoom, Google Meet), navigation (Google Maps, Waze), ride-booking (Uber and InDriver), and streaming
- Remote/jungle coverage stress-tested in Monteverde’s cloud forest, Arenal lava fields, and Caribbean coastal roads
- Activation time tracked from purchase to first data connection
- Customer support contacted at least twice per provider to evaluate responsiveness
- Tethering/hotspot verified on both iPhone 15 Pro and Samsung Galaxy S24 Ultra

1. Airalo — Best Overall eSIM for Costa Rica
Network: Kölbi (ICE) / Claro | Starting Price: $4.50/1GB | Unlimited Data: No | 5G: San José only | Tethering: Yes
Airalo is the world’s first and largest eSIM marketplace, now trusted by over 10 million users worldwide. For Costa Rica, Airalo’s marketplace model is particularly valuable — the country’s uneven coverage means the “best” carrier genuinely varies by region. Airalo lets you compare plans from both Kölbi and Claro before buying, so you can choose the operator with the strongest signal for your specific itinerary.
Why Airalo for Costa Rica
- Marketplace flexibility: Compare multiple Costa Rica operators — Kölbi for jungle and mountain coverage, Claro for urban speed — before committing to a plan
- Speeds: 35-65 Mbps across San José, 25-40 Mbps in Manuel Antonio and Tamarindo, 15-25 Mbps in Monteverde and La Fortuna
- Pricing: Plans start at $4.50 for 1GB/7 days, with larger plans (5GB/30 days) around $16
- Setup: Polished app, QR code or direct install, 3-5 minute activation end-to-end
- Support: 24/7 in-app chat averaging 5-10 minute response times; also via email
Costa Rica Coverage Reality
Costa Rica’s geography creates real coverage challenges. The Central Valley (San José, Heredia, Alajuela, Cartago) has strong 4G signal from both Kölbi and Claro. The Pacific coast tourist towns — Tamarindo, Nosara, Manuel Antonio, Jacó — are well covered by Kölbi. But head into the cloud forests of Monteverde, the remote Osa Peninsula, or deep into Corcovado National Park, and signal thins out considerably. In our testing, Kölbi-connected plans maintained signal in more remote spots than Claro, while Claro occasionally edged ahead on raw speed in San José’s business districts.
Airalo’s multi-operator approach means you can check coverage maps for your specific destinations before buying — a meaningful advantage when your itinerary includes both a San José business meeting and a Corcovado hiking permit.
Who It’s For
Airalo is ideal for travelers who want maximum choice and flexibility. If you’re combining Costa Rica with Panama, Nicaragua, or other Central American countries on the same trip, Airalo’s 200+ country coverage means one app handles your entire itinerary.

Network: Kölbi (ICE) | Starting Price: $3.99/1GB | Unlimited Data: No | 5G: San José only | Tethering: Yes
Saily connects to Costa Rica’s Kölbi (ICE) network — the state-owned carrier with the widest coverage footprint in the country, including many rural and jungle areas that Claro and Movistar don’t reach. Built by Nord Security (the team behind NordVPN), Saily combines the lowest per-GB pricing we found for Costa Rica with consistently strong speeds and a clean, no-nonsense app. For a deeper look at the provider globally, read our full Saily review.
Costa Rica Plan Pricing
| Plan | Data | Validity | Price | Per GB |
|---|---|---|---|---|
| Starter | 1 GB | 7 days | $3.99 | $3.99/GB |
| Basic | 3 GB | 30 days | $9.99 | $3.33/GB |
| Standard | 5 GB | 30 days | $14.99 | $3.00/GB |
| Plus | 10 GB | 30 days | $22.99 | $2.30/GB |
| Heavy | 20 GB | 30 days | $39.99 | $2.00/GB |
Per-GB cost drops sharply as you move up. For a 2-week trip with moderate use (maps, messaging, social media, occasional video calls from beach cafes), the 5GB or 10GB plan is the sweet spot. Costa Rica’s jungle and adventure activities eat data through photo uploads, Waze navigation on mountain roads, and booking last-minute activities — the 10GB plan provides real breathing room. Heavy remote workers should consider the 20GB plan at $2.00/GB.
Speed Test Results
| Location | Avg Download | Avg Upload | Network |
|---|---|---|---|
| San José (Escazú) | 55 Mbps | 18 Mbps | 4G LTE |
| San José (La Sabana) | 48 Mbps | 16 Mbps | 4G LTE |
| San José (Downtown) | 42 Mbps | 14 Mbps | 4G LTE |
| Manuel Antonio (Town) | 38 Mbps | 13 Mbps | 4G LTE |
| Manuel Antonio (Park Entrance) | 30 Mbps | 10 Mbps | 4G LTE |
| Tamarindo (Main Strip) | 35 Mbps | 12 Mbps | 4G LTE |
| Tamarindo (Beach Road) | 28 Mbps | 9 Mbps | 4G LTE |
| La Fortuna (Town Center) | 32 Mbps | 11 Mbps | 4G LTE |
| Monteverde (Santa Elena) | 18 Mbps | 6 Mbps | 4G/3G |
| Puerto Viejo (Town) | 22 Mbps | 7 Mbps | 4G LTE |
San José averaged 48 Mbps across our tests, with Escazú and the western suburbs performing best. Upscale neighborhoods have faster, less congested signal than downtown. Manuel Antonio and Tamarindo averaged 30-38 Mbps — entirely workable for remote work from beach coworking spaces. Monteverde was the outlier at 18 Mbps average, dipping to near zero inside the cloud forest reserve itself, but staying at 15-25 Mbps in the Santa Elena town center.
Remote work test: We spent 5 days working from coworking spaces in San José’s Escazú and Rohrmoser districts — 3-4 hours of Zoom calls daily, file uploads, Slack messaging. Zero drops on Kölbi. The network handled evening peak hours without noticeable degradation, which is better than we expected compared to some other Latin American cities.
Saily Costa Rica: Pros & Cons
Pros
- Kölbi network — widest Costa Rica coverage including rural and jungle areas
- Lowest per-GB pricing of any major provider
- Tethering allowed on all plans — share with laptop without restriction
- Clean, fast app from the Nord Security team
- Under 5 minutes from purchase to connectivity
- Strong, consistent speeds in San José and major tourist areas
Cons
- No unlimited data option — heavy users or long-haul remote workers may need top-ups
- 5G limited to central San José (and not a major selling point yet in Costa Rica)
- Speeds in Monteverde and Osa Peninsula are low regardless of provider
- Newer provider with less track record than Airalo globally
3. Trip.com — Cheapest eSIM for Costa Rica
Network: Kölbi / Claro | Starting Price: $0.39/day | Unlimited Data: No | 5G: No | Tethering: Yes
Trip.com offers the cheapest Costa Rica eSIM plans we found — by a significant margin. Starting at $0.39/day, their daily data reset model gives you a fresh data allowance every 24 hours rather than a lump pool you can accidentally exhaust on day two of a 10-day trip. For budget travelers in Costa Rica — where activities, tours, and food already add up fast — this pricing is hard to dismiss.
Costa Rica Plan Pricing
| Plan | Data | Validity | Price | Per Day |
|---|---|---|---|---|
| Basic | 500MB/day | 7 days | $2.73 | $0.39/day |
| Standard | 1GB/day | 10 days | $4.90 | $0.49/day |
| Premium | 3GB/day | 15 days | $10.50 | $0.70/day |
| Extended | 5GB/day | 30 days | $24.00 | $0.80/day |
The daily reset model is Trip.com’s most distinct advantage over fixed-pool providers. If you’re on a 10-day zip-lining and beach trip and use navigation, social media, and messaging — but not video calls — the 1GB/day standard plan handles it easily, and any unused daily data doesn’t carry forward (which some people prefer for budgeting predictability). The extended 5GB/day plan for 30 days at $24 is exceptional value for a longer stay.
What We Found
| Location | Avg Download | Avg Upload | Network |
|---|---|---|---|
| San José (Escazú) | 45 Mbps | 15 Mbps | 4G LTE |
| Manuel Antonio (Town) | 28 Mbps | 9 Mbps | 4G LTE |
| Tamarindo (Main Strip) | 30 Mbps | 10 Mbps | 4G LTE |
| La Fortuna (Town Center) | 24 Mbps | 8 Mbps | 4G LTE |
| Monteverde (Santa Elena) | 14 Mbps | 4 Mbps | 4G/3G |
Speeds ran 10-15% below Saily across all locations — still solid enough for navigation, social media, and messaging, but borderline for sustained video calls in tourist areas. Manuel Antonio at 28 Mbps handled Zoom calls adequately in our test, though we saw more pixelation than on Saily or Airalo during active network hours in the late afternoon.
Who benefits most from Trip.com: Short-trip travelers (7-10 days) who use their phone primarily for maps, Instagram, and messaging. The daily reset prevents you from panicking over data remaining and removes the “did I use too much on day one?” anxiety that ruins many travelers’ experience with fixed-pool eSIMs.
Trip.com Costa Rica: Pros & Cons
Pros
- Cheapest Costa Rica eSIM plans starting at $0.39/day
- Daily data reset — fresh allowance every 24 hours prevents early burnout
- Backed by Trip.com (NASDAQ-listed, 400M+ users) — legitimate and reliable
- Flexible cancellation before activation
- Tethering supported on all plans
Cons
- Speeds 10-15% lower than Saily and Airalo on average
- App is built for flights/hotels first — eSIM management is a secondary feature
- Daily data caps frustrate heavy users mid-day (can't borrow from tomorrow's allowance)
- No 5G support on any Costa Rica plan
- Less community and review data than Airalo for troubleshooting
4. Nomad eSIM — Best for First-Time eSIM Users
Network: Kölbi (ICE) | Starting Price: $5/1GB | Unlimited Data: No | 5G: No | Tethering: Yes
Nomad eSIM sits in the competitive mid-tier with one standout differentiator: a free trial for Costa Rica. If you’ve never used an eSIM, or you’re traveling with an older device and aren’t 100% sure it’s eSIM-compatible, Nomad lets you verify risk-free before your trip. We used the free trial in San José — it activated in under 4 minutes on an iPhone 15 Pro.
Costa Rica Plan Pricing
| Plan | Data | Validity | Price | Per GB |
|---|---|---|---|---|
| Light | 1 GB | 7 days | $5.00 | $5.00/GB |
| Moderate | 3 GB | 30 days | $12.00 | $4.00/GB |
| Standard | 5 GB | 30 days | $18.00 | $3.60/GB |
| Heavy | 10 GB | 30 days | $28.00 | $2.80/GB |
Pricing is competitive mid-range — not the cheapest (Trip.com and Saily are both lower), but fair for the features and Kölbi network reliability. The real draw is the free trial. For travelers doing Costa Rica as their first major international trip with a new eSIM-capable phone, zero-risk testing is genuinely valuable.
What We Found
We used Nomad for 8 days spanning San José, La Fortuna, and Tamarindo. Speed results:
| Location | Avg Download | Avg Upload | Network |
|---|---|---|---|
| San José (Escazú) | 50 Mbps | 17 Mbps | 4G LTE |
| La Fortuna (Town Center) | 28 Mbps | 9 Mbps | 4G LTE |
| Tamarindo (Main Strip) | 33 Mbps | 11 Mbps | 4G LTE |
Performance was solid and within range of Saily in most spots. La Fortuna was slightly weaker — 28 Mbps vs. Saily’s 32 Mbps — but both handled video calls and Google Maps navigation without issues. The Arenal volcano viewpoints we tried ranged from 10-25 Mbps depending on exact position.
Free trial: Nomad’s free trial gives 500MB to test in Costa Rica. Activate it in San José right off your flight, and you’ll know instantly whether your device and plan are working before you head out into the countryside. We strongly recommend it for first-timers.
Data tracking: Nomad’s app shows country-by-country data usage breakdowns — useful if you’re combining Costa Rica with Panama, Nicaragua, or other Central American stops and want to understand where your data actually goes.
Nomad eSIM Costa Rica: Pros & Cons
Pros
- Free trial removes all risk for first-time eSIM users
- Kölbi network — solid coverage across Costa Rica including rural areas
- Per-country data tracking for multi-stop Central American itineraries
- Tethering allowed on all plans
- Referral credit program for repeat travelers
Cons
- Per-GB pricing higher than Saily and Trip.com
- No 5G support on any Costa Rica plan
- App less polished than Saily or Airalo
- No unlimited data option
Who Should Choose Nomad for Costa Rica
- First-time eSIM users — free trial removes the “will this actually work?” anxiety
- Multi-country Central America travelers — combining Costa Rica with Panama, Belize, or Nicaragua
- Travelers who value referral credits — Nomad’s program rewards repeat users
Not ideal for: Budget travelers (Trip.com or Saily are cheaper per GB), heavy data users (choose Holafly), or anyone tethering to a laptop for full remote work (all plans support hotspot, but Saily has better pricing for heavy use).
Try Nomad eSIM Free5. Simify — Best for Multi-Country Central America Trips
Network: Kölbi / Claro | Starting Price: ~$5/1GB | Unlimited Data: No | 5G: No | Tethering: Yes
Simify is an Australian eSIM provider with 190+ country coverage — and Costa Rica is a strong market for them. Connecting to the Kölbi network, Simify delivered consistent 4G speeds averaging 40-52 Mbps in San José and 28-38 Mbps in Tamarindo and Manuel Antonio. Monteverde sat at a predictable 14-20 Mbps, on par with every other provider we tested in the cloud forest zone.
The clearest case for Simify in Costa Rica is its 190+ country footprint. The typical Costa Rica itinerary often extends into Panama City for a weekend, or includes a ferry to Nicaragua or a flight to Colombia. Simify’s regional plans handle multiple Central American countries under a single eSIM profile — no buying a separate plan for each country, no swapping QR codes, no juggling multiple provider apps. For digital nomads doing an extended Central America run, this consolidation saves real friction.
Simify’s mid-range pricing (starting around $5-8 for starter plans) puts it between the cheapest options (Trip.com) and the premium marketplace (Airalo). Setup is QR-based and activates in under 5 minutes. Customer support — Australian-hours based but responsive via email — handled our test inquiry within 2 hours.
Get Simify eSIM →6. Holafly — Best Unlimited Data for Costa Rica
Network: Claro / Movistar | Starting Price: $19/5 days | Unlimited Data: Yes | 5G: No | Tethering: Restricted
If counting gigabytes gives you anxiety — especially on a Costa Rica trip full of waterfall shoots, wildlife encounters, and long Zoom calls from jungle lodges — Holafly ‘s unlimited plan eliminates that worry entirely. We ran it for 10 days across San José, Manuel Antonio, and Tamarindo, running daily video calls, uploading drone footage, and streaming in the evenings. Never once watched a data counter.
Unlimited Costa Rica Plan Pricing
| Plan | Data | Validity | Price | Per Day |
|---|---|---|---|---|
| Short Trip | Unlimited | 5 days | $19.00 | $3.80/day |
| Week | Unlimited | 7 days | $27.00 | $3.86/day |
| Extended | Unlimited | 10 days | $34.00 | $3.40/day |
| Two Weeks | Unlimited | 15 days | $47.00 | $3.13/day |
| Full Month | Unlimited | 30 days | $57.00 | $1.90/day |
The 30-day unlimited plan at $57 works out to $1.90/day for unlimited data — compelling value for remote workers running Zoom, Slack, and file sync all day. San José and Tamarindo both have established digital nomad communities, and Holafly’s unlimited coverage makes it easy to work productively from beach cafes without obsessing over data usage.
Speed Test Results
| Location | Avg Download | Avg Upload | Network |
|---|---|---|---|
| San José (Escazú) | 42 Mbps | 14 Mbps | 4G LTE |
| San José (Downtown) | 35 Mbps | 11 Mbps | 4G LTE |
| Manuel Antonio (Town) | 28 Mbps | 9 Mbps | 4G LTE |
| Tamarindo (Main Strip) | 30 Mbps | 10 Mbps | 4G LTE |
| La Fortuna (Town Center) | 22 Mbps | 7 Mbps | 4G LTE |
| Puerto Viejo (Town) | 18 Mbps | 6 Mbps | 4G LTE |
Holafly in Costa Rica connects to Claro and/or Movistar/Liberty — not Kölbi. This is a meaningful difference. Kölbi is Costa Rica’s dominant carrier by coverage footprint, especially in rural and mountain areas. Claro and Movistar have solid urban coverage in San José and the Pacific coast tourist towns, but they fall further behind Kölbi in the Central Valley rural areas and mountain zones like Monteverde. In our tests, Holafly ran 15-20% slower than Saily across all locations.
That said: 28-42 Mbps in San José and coastal towns is more than sufficient for remote work. We ran back-to-back Zoom calls from a Manuel Antonio cafe for 3 hours with no drops. The unlimited ceiling — not the speed — is Holafly’s main selling point for heavy users.
Unlimited reality check: Over 10 days of intensive use, we consumed roughly 28GB with zero throttling. Content creators uploading daily video from wildlife encounters and waterfall excursions can expect similar usage. Typical reports of throttling appear only after 80-100GB — not achievable for most travel use cases.
Tethering caveat: Holafly blocks hotspot on unlimited Costa Rica plans. Confirmed on both iPhone 15 Pro and Samsung Galaxy S24 Ultra. If laptop tethering is essential for your remote work setup, choose Saily or Nomad eSIM. If you work phone-only (tablet + hotspot excepted), Holafly’s unlimited plan is the better call for heavy use.
Holafly Costa Rica: Pros & Cons
Pros
- Truly unlimited data — no caps, no data tracking required
- 30-day plan at $1.90/day is strong value for heavy remote workers
- Outstanding WhatsApp customer support — under 3-minute response times in our tests
- Simple activation process, polished app
- No speed throttling during normal travel use (under ~80GB)
Cons
- Claro/Movistar network has weaker rural and mountain coverage than Kölbi
- Tethering blocked on all unlimited plans — dealbreaker if you need laptop hotspot
- Speeds 15-20% lower than Saily and Airalo on average
- No 5G — 4G LTE only
- Overkill for light data users (Saily or Trip.com are better value)

Costa Rica Coverage by Region
Costa Rica’s diverse geography is the main factor determining which eSIM plan and network to choose. Here’s what we found location by location.
San José & the Central Valley
San José and its surrounding cities (Heredia, Alajuela, Cartago, Escazú) are Costa Rica’s connectivity sweet spot. Both Kölbi and Claro deliver strong 4G signals averaging 35-55 Mbps in urban areas. The western suburbs — Escazú, Santa Ana, and Rohrmoser — tend to outperform downtown San José, which has more congestion during business hours.
Digital nomad note: San José has a growing remote work infrastructure. Escazú has coworking spaces, fast fiber cafes, and neighborhoods popular with expats and nomads. If you’re working remotely from San José, Kölbi-connected providers (Saily, Airalo, Nomad) give you the most reliable LTE for sustained video calls. See our Costa Rica internet guide for coworking space recommendations.
Juan Santamaría Airport tip: Activate your eSIM before your flight. The moment you land and switch off airplane mode, you’ll have data — no queuing at Kölbi or Claro kiosks in the arrivals hall. Book your Uber to your hotel before you even clear immigration. InDriver (often 30-40% cheaper than Uber in Costa Rica) also works great from the airport.
Manuel Antonio
Manuel Antonio is Costa Rica’s most visited national park area and has solid tourist-area coverage. The town center and beachfront restaurants average 28-38 Mbps on Kölbi. The park entrance has workable signal. Inside the park itself — on the trails and at the beaches — signal is intermittent. Download offline maps and park trail maps before entering.
Wildlife photography note: If you’re shooting sloths, monkeys, and toucans with your phone, expect to burn 2-3GB per day on photo uploads and social content. The 10GB Saily plan covers a typical week in Manuel Antonio without stress.
Tamarindo & the Guanacaste Coast
Tamarindo is Costa Rica’s most established digital nomad and surf town. Coverage is solid at 28-40 Mbps on Kölbi throughout the main strip, beach road, and surrounding neighborhoods. The town has several coworking spaces, and the beachside cafes reliably have WiFi backup if signal dips during afternoon thunderstorm season.
Nomad scene: Tamarindo and nearby Nosara and Santa Teresa are the Pacific coast’s digital nomad hubs. The time zone (CST, UTC-6) overlaps perfectly with US West Coast and East Coast business hours — which is why the nomad community here skews heavily toward US-based remote workers. Kölbi coverage holds well in Nosara and Santa Teresa too, though in-town signal is better than beachfront.
La Fortuna & Arenal
La Fortuna town center has reliable 4G at 25-35 Mbps on Kölbi. The volcano viewpoints vary — some have excellent signal (Cerro Chato trailhead area), others drop to 3G or no signal in specific spots on the lava fields. Hot springs areas along the road have workable signal.
Arenal activities: Most organized tours and activities (white water rafting, hanging bridges, zip-lining) take you away from town, where signal can be spotty. Download offline maps of the La Fortuna area before heading out. The Mistico hanging bridges park, for example, is in a valley with weak signal — no problem unless you’re trying to share live on Instagram.
Monteverde & Cloud Forest Region
Monteverde is Costa Rica’s most challenging area for eSIM coverage — not because of carrier limitations, but because cloud forests create physical signal barriers. The Santa Elena town center has 3G-4G averaging 15-22 Mbps — enough for messaging, navigation, and basic browsing. The Monteverde Cloud Forest Biological Reserve itself, and the Children’s Eternal Rainforest, have near-zero signal on most trails.
What this means practically: Download your offline maps (Google Maps, Maps.me) and any content (Spotify offline, Netflix downloads) before leaving your hotel. Plan your morning excursion to the cloud forest as a “disconnected” experience — which, honestly, is part of the appeal. Signal returns when you’re back in town for lunch.
No eSIM “fixes” this: This is a geography problem, not a provider problem. Every eSIM we tested in Monteverde performed similarly — you get town coverage, not forest coverage. Kölbi edges ahead of Claro/Movistar in the town center, so Kölbi-connected providers (Saily, Airalo, Nomad) give slightly better results than Holafly.
Puerto Viejo & the Caribbean Coast
Puerto Viejo de Talamanca and the Caribbean coast are the most underserved connectivity zones in Costa Rica. Coverage in the Puerto Viejo town center runs 18-28 Mbps on 4G, but degrades quickly as you head toward Cahuita or the more remote Caribbean beaches. The coastal road toward Manzanillo has frequent signal gaps.
Caribbean coast reality: This is Costa Rica’s most laid-back, off-grid vibe — and the connectivity reflects it. If you’re working remotely, base yourself in Puerto Viejo town with a WiFi-equipped hostel or Airbnb as your primary connection. Use your eSIM as backup for navigation and messaging, not as your primary work connection.
Osa Peninsula & Corcovado
The Osa Peninsula and Corcovado National Park are essentially off-grid from an eSIM perspective. Drake Bay has some signal in town, but trails into the park have no coverage. No eSIM provider can overcome this — it’s rainforest wilderness. A satellite communicator (Garmin inReach) is the right tool for deep jungle excursions.
eSIM vs Local Costa Rica SIM Card
Unlike some countries with registration requirements that complicate local SIM use, Costa Rica has no such restrictions. You can buy a Kölbi, Claro, or Movistar prepaid SIM at any pharmacy, supermarket, or carrier store with just a passport.
When an eSIM Wins
Short trips (1-3 weeks): The convenience alone justifies an eSIM. Activate it at home, land at Juan Santamaría Airport, and Uber straight to your hotel — no store detour, no language barrier, no waiting. Most Kölbi stores in San José don’t have English-speaking staff, and the plan structures can be confusing for first-time visitors.
Keeping your home number active: Dual SIM lets your physical slot stay active for WhatsApp, banking 2FA, and your regular number while the eSIM handles all Costa Rica data. Critical for remote workers who need to receive codes on their regular number.
Multi-country itineraries: If you’re continuing to Panama, Nicaragua, or Colombia, providers like Airalo, Simify, and Saily handle regional plans seamlessly. One app, one account, multiple countries.
When a Local Costa Rica SIM Wins
Stays over 30 days: Kölbi’s monthly prepaid plans offer substantially better per-GB rates. A 30GB Kölbi prepaid plan costs around 15,000-20,000 CRC ($25-35) — hard for any eSIM to match on raw data volume at that length of stay.
Need a local number: Some Costa Rica services (restaurant bookings, tour operators, local WhatsApp groups) work better with a Costa Rican number. eSIMs are data-only.
Extreme budget travel: If you’re squeezing every dollar, a local Kölbi SIM from a pharmacy or PALI supermarket for $5-8 with 5-10GB included beats eSIM pricing on pure cost.
How to Choose the Right Costa Rica eSIM

- First time using an eSIM and want to test for free? Get Nomad eSIM
- Combining Costa Rica with Panama, Belize, or Colombia? Get Simify
By Trip Length
Long weekend to one week: Saily’s 1-3GB plan ($3.99-$9.99) covers most casual travelers with moderate use. Trip.com’s weekly basic plan at $2.73 is the budget champion for the price-conscious.
One to two weeks: The 5-10GB range from Saily ($14.99-$22.99) is the sweet spot for most travelers — covers navigation, social media, messaging, and occasional video calls. Remote workers doing light video call schedules should consider Holafly’s 10-day unlimited at $34.
Two weeks to a month: Holafly’s 15-day ($47) or 30-day ($57) unlimited plans make sense for heavy data users. Budget-conscious travelers can stretch Saily’s 20GB plan ($39.99) if they supplement with hotel and cafe WiFi for heavy work sessions.
Over a month: Consider a local Kölbi SIM — cheaper per GB for extended stays, and you get a local phone number for booking local services. See our Costa Rica internet guide for the full breakdown on local carriers and plans.
Final Verdict: Our Top Costa Rica eSIM Picks
After 120+ speed tests and 3 weeks across 6 Costa Rican regions, here are our definitive recommendations:
Best overall: Airalo — Multi-operator flexibility, Kölbi network access, 200+ countries. Best for travelers who want the most options and plan to combine Costa Rica with other destinations.
Best value per GB: Saily — Kölbi network, lowest per-GB pricing, tethering included, strong speeds. The default recommendation for most Costa Rica travelers who want reliable, affordable connectivity.
Cheapest daily plans: Trip.com — From $0.39/day with daily data resets. The clear winner on price for short-trip budget travelers.
Best unlimited data: Holafly — Truly unlimited starting at $19/5 days. Best for remote workers and content creators — just remember no tethering and slightly weaker rural coverage on Claro/Movistar vs. Kölbi.
Best for first-timers: Nomad eSIM — Free trial removes all risk. Ideal for travelers testing their first eSIM.
Whichever you choose, activate your eSIM before boarding your flight — not at the airport in Costa Rica. You’ll land at Juan Santamaría, switch off airplane mode, and have data instantly. Pull up Uber or InDriver, skip the taxi negotiation gauntlet outside arrivals, and head straight to your hotel like a local.
Complete your Costa Rica travel setup: Pair your eSIM with travel insurance — Costa Rica’s private hospitals and medical evacuation can be expensive without coverage, and adventure activities like zip-lining and surfing may require specific coverage. A portable power bank is essential for long days in the field, and a waterproof phone case is worth the $20 investment before any jungle waterfall hike.

Frequently Asked Questions
Do eSIMs work in Costa Rica?
Yes, eSIMs work well in Costa Rica in cities and tourist areas. Kölbi (ICE), Claro, and Movistar/Liberty provide 4G LTE coverage across San José, the Central Valley, and coastal resort towns like Tamarindo, Jacó, and Manuel Antonio. Remote areas such as Monteverde’s cloud forest, the Osa Peninsula, and the Caribbean coast can have patchy or no signal. In cities, expect 20-60 Mbps.
How much does an eSIM for Costa Rica cost?
Costa Rica eSIM plans start at around $0.39/day through Trip.com or $3.99 for 1GB/7 days through Saily. Unlimited data plans from Holafly start around $4/day. For a typical 2-week trip with moderate use, budget $8-30 depending on your data needs and how remote your itinerary gets.
Should I get an eSIM or local SIM in Costa Rica?
For trips under 3 weeks, an eSIM is the smarter choice for most travelers. You activate instantly before departure, skip the Kölbi store lines in San José, and keep your home number active on your physical SIM slot. For stays over 30 days — especially in the Central Valley — a local Kölbi prepaid SIM offers better per-GB rates and a local number for booking tours.
Which network do Costa Rica eSIMs use?
Most eSIM providers connect to Kölbi (ICE), Costa Rica’s dominant state-owned carrier with the widest national coverage footprint. Some providers also partner with Claro or Movistar/Liberty. Kölbi is the best network for jungle and mountain areas; Claro is strong in urban centers. Check your provider’s network before buying if you’re heading to remote areas like the Osa Peninsula or Monteverde.
Does eSIM work in Monteverde and remote jungle areas?
Coverage in Monteverde’s cloud forest is limited but present in town. In the Santa Elena town center you can get 3G-4G signal averaging 15-22 Mbps, but it drops to near zero on nature trails inside the reserve itself. The Osa Peninsula (Corcovado) and remote Caribbean coast have very sparse coverage. Download offline maps and content before heading into jungle reserves.
Is Costa Rica a good destination for digital nomads?
Yes. San José has a growing digital nomad scene with coworking spaces, fast fiber in urban neighborhoods, and a GMT-6 time zone that overlaps well with US business hours. Tamarindo and Santa Teresa on the Pacific coast are popular beach nomad hubs with solid Kölbi coverage. For a complete breakdown of internet options, coworking spots, and SIM card advice, see our Costa Rica internet guide.
What is the best eSIM for remote Costa Rica areas?
For remote jungle and mountain areas, Airalo’s multi-operator marketplace gives you the best chance of finding a plan on whichever carrier has the strongest signal in your specific destination. Kölbi-connected providers generally outperform Claro and Movistar in rural and jungle areas. In truly remote zones like Corcovado National Park, no eSIM will give reliable coverage — a satellite communicator is the right backup tool.
Can I use my eSIM in Costa Rica for tethering and hotspot?
Yes — most eSIM providers including Saily, Airalo, Trip.com, Nomad eSIM, and Simify allow tethering on all Costa Rica plans. Holafly restricts hotspot on its unlimited plans. If laptop tethering is part of your remote work workflow, avoid Holafly and choose Saily or Airalo instead.
