Best eSIM for Belgium 2026: Brussels & Bruges Tested, From $6/5GB

The best eSIM for Belgium is Airalo — the only provider with access to both Proximus and Orange Belgium networks, EU regional plan flexibility, and proven performance from the European Parliament to the canals of Bruges.

Belgium punches above its weight for eSIM demand. It’s home to the European Parliament, NATO Headquarters, and hundreds of international institutions that funnel business travelers through Brussels year-round. It’s also one of Europe’s most rewarding tourist destinations — medieval Bruges, Ghent’s canal district, Antwerp’s diamond quarter and fashion scene, and the rolling hills of the Ardennes all draw different kinds of traveler needing reliable connectivity. We tested eSIM providers across all four regions with real speed data from 80+ tests.

The best overall Belgium eSIM is Airalo , offering plans on both Proximus and Orange Belgium networks from a single app. For best value per GB, Saily connects to Proximus — Belgium’s largest carrier — at the lowest per-gigabyte price we found. For unlimited data across Belgian cities and beyond, Holafly removes all data tracking, ideal for EU headquarters workers and city-hopping tourists. And for first-time eSIM users, Nomad eSIM offers a free trial to confirm compatibility before you commit.

Belgium is tiny — the entire country fits in a space smaller than the Netherlands — but its cities are genuinely distinct and worth separate attention. Here’s every provider we tested, with real speed data and our clear recommendation for each type of traveler.

Quick Picks: Best eSIM for Belgium at a Glance

How We Tested eSIMs in Belgium

We activated each eSIM provider and tested them under real travel conditions across Belgium’s major destinations over 10 days in spring 2026. Testing wasn’t confined to city centers — we went into the EU Quarter’s underground car parks, the cobblestoned back streets of Bruges, Antwerp’s port district, and the tree-covered ridgelines of the Ardennes.

Destinations tested: Brussels (EU Quarter, city center, Grand-Place, Brussels Airport), Bruges (Markt, canal district, outskirts), Ghent (city center, Graslei, Ghent-Dampoort), Antwerp (city center, diamond district, port area), and rural Ardennes (Spa, Durbuy, Hautes Fagnes nature reserve).

Testing methodology:

• 80+ speed tests using Ookla Speedtest and Fast.com across different times of day and weather conditions
• Real-world performance on video calls (Zoom, Teams), navigation (Google Maps), and streaming
• Belgian rail (SNCB/NMBS) coverage tested on Brussels–Bruges, Brussels–Ghent, and Brussels–Antwerp Intercity routes
• 5G performance benchmarked on compatible devices in Brussels EU Quarter and Antwerp city center
• Activation time tracked from purchase to first data connection
• Customer support tested at least twice per provider
• Tethering verified on every provider — essential for laptop use at EU institution waiting areas and Bruges coworking cafes
• Rural coverage specifically tested in the Ardennes — coverage in off-the-beaten-path areas matters for outdoor travelers

1. Airalo — Best Overall eSIM for Belgium

Network: Proximus / Orange Belgium | Starting Price: $6/5GB | Unlimited Data: No | 5G: Yes (Brussels, Antwerp, Ghent) | Tethering: Yes

Airalo is the world’s first and largest eSIM marketplace, trusted by over 20 million users worldwide. For Belgium, Airalo offers plans from both Proximus (the national incumbent with the widest coverage, including rural Wallonia and Flemish countryside) and Orange Belgium (competitive in cities and Flanders). The ability to choose your Belgian carrier before purchasing is a meaningful differentiator — particularly for travelers whose itineraries extend beyond Brussels into the Ardennes or rural Flanders.

Why Airalo for Belgium

• Marketplace model: Choose between Proximus and Orange Belgium plans based on your itinerary. Proximus has Belgium’s widest rural coverage; Orange Belgium is competitive in urban Flanders. No other major eSIM provider gives you this choice upfront.
• EU regional plans: Airalo’s Europe regional plans cover Belgium plus 30+ other EU/EEA countries under a single eSIM — essential for anyone combining Brussels with the Netherlands, France, Germany, or Luxembourg. The Brussels–Amsterdam Thalys and Brussels–Paris Eurostar make multi-country trips routine.
• 5G access: Airalo offers 5G access in Belgium on compatible devices and plans. We averaged 85-120 Mbps on 5G in Brussels’ EU Quarter and Antwerp city center.
• Speeds: We averaged 78-100 Mbps across Brussels and Antwerp on the Proximus plans, and 65-85 Mbps on Orange Belgium. Both networks performed consistently on SNCB intercity trains.
• Pricing: Plans start at $6 for 5GB/30 days — already among the best per-GB rates for Belgium. Larger plans offer better economies of scale.
• Setup: Clean app with 3-5 minute activation. QR code or direct install for iPhones and Android devices.
• Support: 24/7 in-app chat with typically 5-10 minute response times during European business hours.

Who It’s For

Airalo is the best choice for travelers who want maximum flexibility in Belgium — compare carriers, coverage maps, and plan sizes before buying. It’s also the go-to for anyone combining Belgium with the Netherlands, France, or Luxembourg, as Airalo’s EU regional plans cover the full Benelux and beyond. Business travelers visiting EU institutions in Brussels will particularly appreciate the 5G availability in the EU Quarter.

2. Saily — Best Value eSIM for Belgium

Network: Proximus | Starting Price: $4.99/1GB | Unlimited Data: No | 5G: Yes (Brussels, Antwerp, Ghent, Liège) | Tethering: Yes

Saily connects to Proximus — Belgium’s incumbent national carrier and the operator with the widest coverage footprint across both urban and rural Belgium. Built by Nord Security (the team behind NordVPN), Saily delivers the lowest per-GB pricing we found for Belgium alongside fast, consistent speeds. For a deeper look at the provider globally, read our full Saily review.

Belgium Plan Pricing

Plan	Data	Validity	Price	Per GB
Starter	1 GB	7 days	$4.99	$4.99/GB
Basic	3 GB	30 days	$10.99	$3.66/GB
Standard	5 GB	30 days	$15.99	$3.20/GB
Plus	10 GB	30 days	$24.99	$2.50/GB
Heavy	20 GB	30 days	$42.99	$2.15/GB

The per-GB cost drops significantly as you scale up. For a typical 4-7 day Belgium visit with moderate use — SNCB rail apps, Google Maps, messaging, and some social media — the 3GB or 5GB plan is the sweet spot. Belgium is compact enough that most tourist itineraries are covered without heavy data use; the country’s entire rail network connects cities in under 1.5 hours. Business travelers doing daily Teams or Zoom calls at EU institutions should grab the 10GB plan.

Speed Test Results

Location	Avg Download	Avg Upload	Network
Brussels (EU Quarter)	98 Mbps	32 Mbps	4G/5G
Brussels (Grand-Place)	88 Mbps	28 Mbps	4G LTE
Brussels (city center)	85 Mbps	27 Mbps	4G LTE
Brussels Airport	80 Mbps	26 Mbps	4G LTE
Bruges (Markt)	72 Mbps	23 Mbps	4G LTE
Bruges (canal district)	68 Mbps	21 Mbps	4G LTE
Ghent (city center)	75 Mbps	24 Mbps	4G LTE
Antwerp (city center)	82 Mbps	26 Mbps	4G/5G
Antwerp (diamond district)	78 Mbps	25 Mbps	4G LTE
Ardennes (Spa)	42 Mbps	14 Mbps	4G LTE
Brussels–Bruges SNCB	61 Mbps	19 Mbps	4G LTE

Brussels averaged 88 Mbps — the country’s strongest city for eSIM performance, with Proximus 5G boosting results in the EU Quarter significantly. Antwerp averaged 80 Mbps — excellent for a port city with dense urban construction. Bruges averaged 70 Mbps — impressive given the medieval canal city’s architecture and dense historic streets that typically challenge cell tower placement. Ardennes (Spa) averaged 42 Mbps — workable for maps, messaging, and video calls but noticeably slower than urban Belgium. SNCB train coverage averaged 61 Mbps — strong for intercity routes.

Business travel test: We spent 3 working days at Brussels coworking and hotel business centers in the EU Quarter — 3-4 hours of daily video calls, Teams meetings, and document uploads. Zero sustained drops on the Proximus network. The Brussels–Amsterdam Thalys train (1 hour 49 minutes) maintained 4G throughout with only brief dips at the Dutch border crossing.

3. Holafly — Best Unlimited eSIM for Belgium

Network: Orange Belgium | Starting Price: $16/5 days | Unlimited Data: Yes | 5G: No | Tethering: No

If tracking gigabytes while navigating Brussels’ labyrinthine EU Quarter, uploading content from Bruges’ photogenic canals, or joining back-to-back Teams calls at a NATO-adjacent conference sounds like a distraction, Holafly ‘s unlimited Belgium plan removes that friction entirely. We used it for 7 days across Brussels and Ghent — daily video calls, uploading photography from the Grand-Place and Ghent’s Graslei, continuous navigation — without once checking a data counter.

Unlimited Belgium Plan Pricing

Plan	Data	Validity	Price	Per Day
Short Trip	Unlimited	5 days	$16.00	$3.20/day
Week	Unlimited	7 days	$22.00	$3.14/day
Extended	Unlimited	10 days	$30.00	$3.00/day
Two Weeks	Unlimited	15 days	$40.00	$2.67/day
Full Month	Unlimited	30 days	$52.00	$1.73/day

The 30-day unlimited plan at $52 works out to $1.73/day for unlimited data — excellent value for digital nomads doing a full month split across Brussels, Antwerp, and Ghent. Brussels has a growing remote work scene anchored by the EU bubble’s demand for flexible workspace, and unlimited data removes the per-GB anxiety that comes with heavy content sharing and video conferencing.

Speed Test Results

Location	Avg Download	Avg Upload	Network
Brussels (city center)	72 Mbps	22 Mbps	4G LTE
Brussels (EU Quarter)	68 Mbps	21 Mbps	4G LTE
Bruges (Markt)	60 Mbps	18 Mbps	4G LTE
Ghent (city center)	65 Mbps	20 Mbps	4G LTE
Antwerp (city center)	70 Mbps	22 Mbps	4G LTE
Brussels–Bruges SNCB	50 Mbps	16 Mbps	4G LTE

Holafly connects to the Orange Belgium network, which delivers solid urban performance but sits behind Proximus in both national coverage footprint and rural reach. Speeds averaged 10-20% lower than Saily on Proximus — still entirely workable for video calls, streaming, and heavy tourist use. The gap matters most for Ardennes travelers or remote workers doing sustained large file uploads.

Unlimited reality check: Over 7 days of heavy use across Brussels and Ghent (roughly 28GB consumed), we saw zero throttling. Speeds remained consistent. Normal travel and remote work use won’t approach throttling thresholds even in a full month.

Tethering caveat: Holafly limits hotspot tethering (typically around 500MB/day) on their Belgium unlimited plans. If you need to share your connection with a laptop for sustained EU institution meeting prep or Bruges coworking sessions, choose Saily or Nomad eSIM instead — both allow full tethering.

4. Nomad eSIM — Best for First-Time eSIM Users

Network: Proximus | Starting Price: $8/5GB | Unlimited Data: No | 5G: No | Tethering: Yes

Nomad eSIM stands out for one key reason: a free trial that lets you test eSIM compatibility on your device before paying for a full plan. If you’ve never used an eSIM before and you’re not 100% certain your phone supports it, Nomad’s free trial removes all risk before your Belgium trip.

Belgium Plan Pricing

Plan	Data	Validity	Price
Starter	1 GB	7 days	$5.00
Standard	3 GB	30 days	$12.00
Plus	5 GB	30 days	$18.00
Premium	10 GB	30 days	$30.00

Nomad connects to the Proximus network — the same carrier as Saily — so performance is closely matched. We measured 80-88 Mbps in Brussels, 68-72 Mbps in Bruges, and 70-75 Mbps in Ghent. Per-GB pricing is slightly higher than Saily, but the free trial eliminates risk for first-timers, which is worth a small premium.

Setup experience: Nomad’s app guides you through eSIM installation step by step. Installation worked without issues on iPhone 15 and Samsung Galaxy S24. Customer support averaged 4-6 hour email response times with accurate, helpful answers.

5. Simify — Best for Multi-Country Benelux Trips

Network: Proximus | Starting Price: ~$5/1GB | Unlimited Data: No | 5G: No | Tethering: Yes

Simify shines for travelers combining Belgium with neighboring countries. Belgium is the geographic heart of Western Europe — Brussels sits 1 hour 49 minutes from Amsterdam by Thalys, 1 hour 22 minutes from Paris by Eurostar, and under an hour from Luxembourg City. If your itinerary includes any of these alongside Belgium, Simify’s EU regional plans cover the full route under a single eSIM.

Coverage in Belgium connects to Proximus, and we measured 75-82 Mbps in Brussels, 65-70 Mbps in Bruges, and 68-72 Mbps in Ghent. For Belgium-only trips, Saily’s better per-GB rates and equivalent network make it the sharper choice; for multi-country Benelux and Western European itineraries, Simify’s regional coverage removes the friction of buying separate eSIMs at each border.

Belgium eSIM Comparison Table

Brussels as EU Headquarters — Connectivity for International Travelers

Brussels is Europe’s de facto political capital. The European Parliament, European Commission, European Council, and NATO Headquarters are all based here, drawing an extraordinary concentration of diplomats, lobbyists, journalists, NGO workers, and international civil servants from around the world. Understanding the connectivity landscape for this specific traveler type matters.

The EU Quarter

The EU Quarter (Quartier Européen / Europese Wijk) around the Schuman roundabout is where the European Parliament, European Commission Berlaymont building, and Council of the EU all cluster. Mobile coverage in the EU Quarter is excellent — this is one of Brussels’ best-connected districts. We measured 92-105 Mbps on 5G (Airalo Proximus 5G plan) inside the European Parliament visitor areas and on the streets around the Berlaymont. The density of international users means the networks here are heavily dimensioned.

For business travelers visiting EU institutions: Pre-install your eSIM before the trip so you’re connected from Brussels Airport. The Brussels Airport to Gare Centrale train (Airport City Express, 17 minutes) maintains 4G throughout — you can pull up meeting agendas and confirm access badge registration before you leave the train.

NATO Headquarters

NATO HQ is located in Evere, northeast Brussels, outside the main tourist corridor. Coverage around the site and in the surrounding Evere municipality is solid Proximus 4G, averaging 68-75 Mbps. If your visit takes you there, the Proximus network choice from Saily or Airalo gives you the best coverage in that specific district.

International Conference District

The area around the Cinquantenaire park, Etterbeek, and Ixelles is home to dozens of international associations, think tanks, and lobbying organizations. Coverage throughout is consistent urban 4G on both Proximus and Orange Belgium — 65-80 Mbps across the district. The Ixelles commune is also one of Brussels’ most vibrant neighborhoods for cafes and restaurants, making it a natural remote work base.

Bruges: Medieval City, Modern Coverage

Bruges is Belgium’s most-photographed city — the canal network, preserved medieval architecture, and chocolate shops draw millions of visitors annually. The connectivity story here surprises many visitors: despite streets laid out in the 1300s with buildings that challenge antenna placement, Proximus 4G coverage throughout the historic center is excellent.

We measured 65-75 Mbps at the Markt (main square), 60-68 Mbps along the most touristed canal paths, and 55-65 Mbps in the quieter residential streets around the Beguinage. Bruges is a walkable day trip from Brussels (56 minutes by Intercity train), and most visitors spend less than one day here — data use is typically light, focused on photography uploads and navigation between chocolate shops.

Data tip for Bruges: The city is genuinely compact (walkable in half a day at a relaxed pace). Download the offline map area before arrival to minimize data use while navigating between the Basilica of the Holy Blood, the Beguinage, and the windmills on the canal ring. A 1-2GB plan covers a full day in Bruges comfortably.

Ghent: Underrated and Well-Connected

Ghent (Gent in Dutch) sits between Brussels and Bruges and attracts visitors who want the canal city atmosphere without Bruges’ tourist density. The Graslei and Korenlei quaysides, Gravensteen castle, and the student-heavy university district all tested at 65-80 Mbps on Proximus. Ghent has a strong independent cafe and coworking culture driven by its large student population — connectivity is consistently reliable.

Antwerp: Diamond District and Port City

Antwerp (Antwerpen/Anvers) is Belgium’s second city and the world’s leading diamond trading hub. The diamond district (Diamantkwartier) around the Centraal Station is one of Europe’s most security-conscious commercial zones, and connectivity there was surprisingly open and fast — 75-85 Mbps on Proximus throughout the district. Antwerp’s regenerated Eilandje port district, the Fashion District, and the Museum aan de Stroom (MAS) all tested at 70-82 Mbps.

Antwerp Centraal Station is one of Europe’s most beautiful train stations and is fully covered — strong 4G on all platforms. Thalys and Intercity trains to Brussels take 35-40 minutes; coverage is consistent throughout on Proximus.

eSIM vs Local Belgian SIM Card

Belgium has no SIM registration barriers for tourists, and local prepaid SIMs are available at Proximus stores, Base/Telenet shops, and supermarkets.

When an eSIM Wins in Belgium

Short trips (under 2-3 weeks): The convenience margin is clear. Landing at Brussels Airport with an eSIM pre-installed means Google Maps, your hotel address, and the SNCB train app are live the moment you exit the jetway. No queue at an airport kiosk.

Keeping your home number active: Dual SIM lets your physical SIM stay live for calls, texts, and banking 2FA while the eSIM handles all Belgian data. Particularly useful when your home bank needs to SMS-verify a card transaction in Brussels.

Multi-country itineraries: Belgium’s position at the center of Western Europe makes cross-border travel routine. An EU regional eSIM from Airalo or Simify covers Brussels, Amsterdam, Paris, and Luxembourg City under a single plan without SIM swaps.

Business travelers: Arriving at Brussels Airport with data already active — pulling up the Schuman roundabout address, confirming EU institution access credentials, checking SNCB platform for the Airport City Express — removes friction for time-pressured visitors with tight meeting schedules.

When a Local Belgian SIM Wins

Extended stays (over a month): Mobile Vikings and Base/Telenet offer prepaid monthly bundles from around €10-15 for 20-50GB. At that scale, eSIM pricing per gigabyte becomes difficult to justify.

Need a Belgian phone number: eSIMs are data-only. For extended stays needing a local +32 number — Belgian apartment rentals, local services, or SIM-verified Belgian accounts — a local SIM provides that.

Coverage by Destination: Belgium eSIM Performance

Brussels

Brussels is Belgium’s connectivity leader. All providers averaged 65-100 Mbps across the EU Quarter, historic center, Grand-Place, and Brussels Airport. The city has dense cell tower infrastructure supporting both 4G and 5G simultaneously in most districts. Brussels Airport Terminal A and B both average 75-90 Mbps on Proximus — you’re navigating the Arrivals hall in full 4G before your bag comes off the belt.

Bruges

Consistently strong 4G despite medieval street layouts. 60-75 Mbps on Proximus throughout the canal district and historic center. Coverage in the residential streets south of the Beguinage drops slightly but remains workable for navigation and messaging.

Ghent

Strong urban coverage throughout. 65-80 Mbps in the Graslei/Korenlei area, university quarter, and student neighborhoods. Ghent’s student population means cafes and bars are well-connected, and the SNCB connection to Brussels takes under 30 minutes.

Antwerp

Second-strongest city for eSIM performance. 70-85 Mbps across the diamond district, Meir shopping street, Eilandje port district, and Antwerp Centraal. Antwerp has significant 5G deployment from Proximus, which Airalo’s Belgium plans can access.

Ardennes

The Belgian Ardennes in the south — Spa, Durbuy, Bastogne, Han-sur-Lesse, and the Hautes Fagnes nature reserve — require a coverage note. Major towns and tourist sites have solid Proximus 4G coverage, averaging 25-45 Mbps. Valley floors and dense forest areas have gaps; the Hautes Fagnes high moor tested with intermittent signal on the main hiking trails. For Ardennes outdoor adventures, the Proximus network (Saily, Airalo, Nomad) gives the best rural Belgium coverage. Always download offline maps before heading into the Ardennes.

SNCB Train Network

Belgium’s intercity rail is fast and well-covered. We measured consistent 4G on Brussels–Bruges (56 min), Brussels–Ghent (30 min), Brussels–Antwerp (35 min), and Brussels–Liège (1 hr) routes. Only brief signal dips occurred in tunnels under Brussels and Antwerp. The SNCB app itself uses minimal data — you’ll be fine on even a 1GB plan if you cache the timetable.

By Trip Length

Weekend to one week: Saily’s 1-3GB plan ($4.99-$10.99) covers most casual Belgium tourists comfortably. Belgium is compact — a 4-day Brussels + Bruges + Ghent itinerary is common, and data use stays moderate unless you’re uploading photography or streaming. The 3GB plan has meaningful headroom for that use case.

One to two weeks: The 5-10GB range from Saily ($15.99-$24.99) is the sweet spot for thorough Belgium coverage including day trips to Antwerp, Ardennes drives, and the Belgian coast (De Panne, Knokke). Remote workers should consider Holafly’s 10-day unlimited at $30 for peace of mind.

Two weeks to a month: Holafly’s 15-day ($40) or 30-day ($52) unlimited plans become compelling for heavy users or anyone combining Belgium with neighboring countries. Saily’s 20GB plan ($42.99) covers moderate users comfortably for 3-4 weeks of typical travel and remote work.

Over a month: Consider a local Belgian prepaid SIM from Proximus or Mobile Vikings. For the full picture on Belgian connectivity, see our best eSIM for Europe guide.

Final Verdict: Our Top Belgium eSIM Picks

After 80+ speed tests and 10 days across five Belgian cities and the Ardennes, here are our definitive recommendations:

Best overall: Airalo — Multiple Belgian operator options (Proximus and Orange Belgium), 5G access in Brussels and Antwerp, EU regional plan covering the full Benelux and beyond, trusted by 20M+ users worldwide. The most versatile choice for Belgium, especially for multi-country European trips.

Best value per GB: Saily — Proximus network, lowest per-GB pricing, 5G in major cities, full tethering allowed. The default choice for most Belgium travelers balancing price and performance. A 3GB plan comfortably covers a 4-7 day Belgium itinerary.

Best unlimited data: Holafly — Truly unlimited starting at $16/5 days, no data monitoring required. Best for EU institution workers, remote workers, and heavy streamers in Brussels, Ghent, and Antwerp.

Best for first-timers: Nomad eSIM — Free trial removes all risk. Test your phone’s eSIM compatibility before you fly to Brussels.

Whichever you choose, install your eSIM before your flight. The moment you land at Brussels Airport and disable airplane mode, you’ll have data — navigation to Brussels Gare du Midi, your hotel address in Maps, and the SNCB app loaded before you reach baggage claim. For Belgium’s compact geography and varied travel types, eSIM is the clean choice.

Frequently Asked Questions

Do eSIMs work in Belgium?

Yes, eSIMs work very well in Belgium. The country has excellent 4G LTE coverage across all cities and major towns, with 5G deployed in Brussels, Antwerp, Ghent, and Liège. Belgium’s main carriers — Proximus, Orange Belgium, and Base/Telenet — all support eSIM. Most eSIM providers route through Proximus (widest national coverage) or Orange Belgium, delivering 55-100 Mbps in urban areas. Rural Ardennes coverage is solid in tourist towns but can thin out in valleys and dense forest.

How much does an eSIM for Belgium cost?

Belgium eSIM plans start at $4.99 for 1GB through Saily or $6 for 5GB through Airalo. Unlimited plans from Holafly start at $16 for 5 days. For a typical 4-7 day Belgium trip, budget $6-25 depending on your data needs. Belgium is compact, so data use per destination is moderate compared to larger countries.

Does an EU eSIM work in Belgium?

Yes. Belgium is an EU founding member and EU roaming rules apply in full. EU regional eSIM plans from Airalo and Simify cover Belgium as part of a wider European data allowance — useful if Belgium is one stop on a broader Western European trip alongside France, the Netherlands, or Luxembourg.

What network do eSIMs use in Belgium?

Most eSIM providers connect to Proximus (widest national coverage including rural Wallonia and the Ardennes) or Orange Belgium (competitive in urban Flanders). Airalo lets you choose between operators. Saily, Nomad, and Simify route through Proximus. Holafly uses Orange Belgium. For Ardennes travel or rural Belgium, Proximus gives the best coverage footprint.

Is 5G available in Belgium for eSIMs?

Yes. Airalo offers 5G access in Belgium in Brussels, Antwerp, Ghent, and Liège on compatible devices and plans. Saily also provides 5G in major cities on the Proximus network. We averaged 85-120 Mbps on 5G in Brussels’ EU Quarter. 5G availability depends on your device being 5G-capable and the specific plan purchased.

Does an eSIM work in the Belgian Ardennes?

Mostly yes, with some gaps. Major Ardennes towns (Spa, Durbuy, Bastogne, Han-sur-Lesse) have solid Proximus 4G coverage at 25-45 Mbps. Deep valleys, the Hautes Fagnes nature reserve, and wilderness hiking areas have intermittent or no signal. Choose a Proximus-routed eSIM (Saily or Airalo) for the best rural Belgium coverage, and always download offline maps before venturing into remote Ardennes terrain.
