About This Calculator
Our travel data calculator estimates your mobile data needs based on real-world usage patterns we measured across 50+ countries. Data consumption varies by app, network quality, and settings -- use this as a starting point and round up 20-30% for safety.
Most travelers underestimate their data needs. Navigation alone uses 80-100 MB/day, and a single hour of video calling burns through 600 MB. This calculator factors in your WiFi availability to give a realistic estimate of how much eSIM data you should purchase.
