Quick check on your iPhone: go to Settings → Mobile Service. If you see 'Add eSIM', your iPhone supports eSIM.
Step 1: Get your eSIM
Start by clicking on MondoMate. The installation flow adjusts automatically depending on what device you're using.

- 4Tap 'Continue' in the dialog that appears on your iPhone
- 5Give your eSIM a label, such as 'MondoMate'
- 6Tap 'Done' to complete the installation
Step 2: Choose your default lines
Once installed, your iPhone has two active lines: your regular SIM and the MondoMate eSIM. iPhone will ask you which line to use for what - here's what to choose:
- Primary line (calls & SMS): your regular SIM - keep this as is
- Mobile data: select MondoMate eSIM - this is what uses your travel data plan
- Use MondoMate as your data line while travelling to avoid expensive roaming charges on your home SIM
Step 3: Set mobile data on iPhone
- 1Go to Settings → Mobile Service
- 2Tap 'Mobile Data'
- 3Select MondoMate eSIM as your active data line
- 4Your regular SIM remains active for calls and SMS - no changes needed
Switching data line takes just seconds. You can switch back and forth at any time from Settings → Mobile Service → Mobile Data.
Step 4: Enable data roaming
Data roaming must be enabled on your MondoMate eSIM for it to connect to partner networks abroad.
- 1Go to Settings → Mobile Service
- 2Tap on your MondoMate eSIM
- 3Enable 'Data Roaming'
Turn data roaming OFF on your primary SIM (your regular SIM card) to avoid unexpected charges from your home operator while abroad.
When you arrive at your destination
Your iPhone will automatically search for and connect to a supported network at your destination.
- Make sure MondoMate eSIM is selected as your mobile data line
- Data roaming must be ON for your MondoMate eSIM
- If data doesn't work immediately, turn Airplane Mode on for 30 seconds, then off again
- If you still have no data, go to Settings → Mobile Service → MondoMate and check that the line is active and roaming is on
