FAQ

Frequently Asked Questions

Everything you need to know about TsunaGo and eSIM technology.

An eSIM (embedded SIM) is a digital SIM built into your phone. Instead of inserting a physical SIM card, you download a data plan directly to your device. It works alongside your existing SIM, so you keep your regular phone number while using a local data connection abroad. Most iPhones from iPhone XS onward support eSIM.
All iPhones from iPhone XS (2018) onward support eSIM. This includes iPhone XS, XS Max, XR, 11 series, 12 series, 13 series, 14 series, 15 series, 16 series, and all SE models from 2020 onward. iPhone 14 and later models sold in the US are eSIM-only with no physical SIM tray.
After purchasing a plan in TsunaGo, the eSIM installs automatically - no QR code scanning needed. You will see a prompt to add the new cellular plan. Tap "Allow" and the eSIM activates within seconds. You can install it before your trip and it will connect as soon as you arrive at your destination.
Yes. TsunaGo eSIM provides data only. Your regular phone number stays active on your primary SIM for calls, texts, and iMessage. You can receive calls and texts on your home number while using TsunaGo for data. Just make sure to set TsunaGo as your data line in Settings > Cellular.
We have a 15-minute guarantee. If your eSIM does not connect within 15 minutes of activation, you get an automatic full refund - no support ticket needed, no questions asked. Our system detects connection issues automatically and processes the refund instantly. You can also contact our support team at any time for help troubleshooting.
TsunaGo is currently available for iPhone only. We are actively developing our Android app and plan to launch it soon. Join our waitlist in the app or email us at support@tsunago.app to be notified when the Android version is available. Most modern Android phones from Samsung, Google Pixel, and OnePlus already support eSIM hardware.
