What are the advantages of using an eSIM for travel?

You get connected before you land - no hunting for SIM shops at the airport. Activation takes seconds with our direct activation link, you keep your home number on your physical SIM, and you avoid expensive roaming charges from your home carrier.

My QR code won't scan - what should I do?

Try the activation link instead - just tap it directly from your email. If you must use the QR code, ensure you're scanning from a screen with full brightness. You can also enter the activation details manually.

My eSIM data is slow - how can I improve it?

Try switching between 4G and 5G in your network settings. Move to a location with better signal. Restart your phone to reconnect to a different tower. Peak hours in busy areas may also affect speeds temporarily.
