When you have both a regular SIM and a MondoMate eSIM active, you need to tell your phone which one to use for mobile data. Here's how to switch on both platforms.
iPhone (iOS)
- 1Go to Settings → Mobile Service
- 2Tap 'Mobile Data'
- 3Select MondoMate eSIM to use it for internet
- 4Your regular SIM remains active for calls and SMS
- 5To switch back, repeat and select your regular SIM
Android
- 1Go to Settings → Network & Internet → SIM Manager
- 2Tap 'Preferred SIM for mobile data' or 'Mobile Data'
- 3Select MondoMate eSIM
- 4To switch back, repeat and select your regular SIM
You only need to switch the data SIM. Calls and SMS will continue to use your regular SIM as long as it stays set as the default voice line.
If your regular SIM is set as the data SIM and roaming is enabled, it may use expensive roaming data in the background. Always double-check your data SIM selection when arriving at a new destination.
