❓ Frequently Asked Questions
Q: How much data do I need for international travel?
A: Data needs vary widely by usage style. Light users (maps + messaging only) use about 200-500MB per day. Moderate users (social media + web browsing) use 1-2GB per day. Heavy users (video streaming + hotspot) may need 3-5GB+ per day. Use our calculator above to estimate based on your specific habits.
Q: What happens if I run out of eSIM data?
A: Most eSIM providers offer top-up options so you can add more data to the same eSIM. You can also buy a larger plan upfront, or carry multiple eSIMs as backup. We recommend adding a 30% buffer to avoid running out mid-trip.
Q: How much data does social media use per hour?
A: Short-form video apps (TikTok, Instagram Reels) use roughly 120-500MB per hour depending on video quality. Photo-based social media uses less. For heavy social media users, consider a plan with 5GB+ data or enable data saver mode.
Q: How much data does video streaming use?
A: SD video (480p-720p) uses about 300MB-1GB per hour. Full HD (1080p) uses 1.5-3GB per hour. 4K streaming can use 5-10GB per hour. If you plan to stream while traveling, consider downloading content on hotel WiFi or choose an unlimited data plan.
Q: Are unlimited data plans really unlimited?
A: Most 'unlimited' plans have a fair usage policy with a high-speed data cap. Once you exceed the cap, speeds are throttled (often to 2G speeds). Always check the fine print for the high-speed data allowance before purchasing.
Q: Does using a hotspot use more data?
A: The hotspot itself doesn't use extra data, but all connected devices share the same data pool. Tethering a laptop can use a lot of data due to background updates and cloud syncing. Only use hotspot when necessary and disable auto-sync on connected devices.
