If the mobile data toggle for your MondoMate eSIM is greyed out or not responding, try these steps in order.
Steps to try
- 1Confirm MondoMate eSIM is selected as the active data SIM in settings (not your home SIM)
- 2Make sure flight mode is off
- 3Toggle flight mode on and off to force a network re-registration
- 4Restart your phone completely
- 5Make sure your device software is up to date
- 6Check that data roaming is enabled specifically on the MondoMate eSIM
- 7Contact support if the issue persists after trying all steps above
On iPhone
Go to Settings → Mobile Service → tap MondoMate eSIM → make sure 'Turn On This Line' is enabled and 'Data Roaming' is on.
Do not delete your eSIM without contacting support first - especially if the plan has already been activated.
