Most connection problems are fixed in your phone's settings. Once you're in the country your plan is for, work through these in order.

  1. Turn on data roaming for the Roamfly eSIM. On iPhone, go to Settings > Mobile Service (Cellular in the US), tap the eSIM and turn on Data Roaming.
  2. Choose the eSIM for mobile data. On iPhone, go to Settings > Mobile Service > Mobile Data (Cellular > Cellular Data in the US). On Android, go to Settings > Network & internet > SIMs. On Samsung, go to Settings > Connections > SIM manager.
  3. Turn airplane mode on, then off again, so your phone reconnects.
  4. Restart your phone.
  5. Check your signal. Move somewhere with better coverage if you can.

Still no connection? Chat with us or email hello@roamfly.co. If your eSIM is installed but not connecting, and we can't fix it within 24 hours, you get a full refund.
