Installation
Install an eSIM and check device compatibility
Install a travel eSIM on iPhone or Android while you have reliable Wi-Fi.
Cannot install your eSIM
Follow these steps in order. Menu names may vary by phone and software version.
1. Check your phone supports eSIM
Your phone must support eSIM and be carrier-unlocked. If you are unsure, send us your phone make and model.
2. Connect to reliable Wi-Fi
Open Settings → Wi-Fi → connect to a trusted network.
If the profile download fails, try another trusted internet connection. Restricted Wi-Fi or a firewall can block the download.
3. Open the eSIM installation screen
iPhone: Settings → Mobile Service (or Cellular) → Add eSIM → Use QR Code
Samsung: Settings → Connections → SIM manager → Add eSIM → Scan QR code
Open your Telroo order on another screen and scan the QR code using the phone where you will use the eSIM. If your order has an Install your eSIM button, you can use it on that phone instead.
This eSIM can only be installed once. Do not scan the QR code on a different phone or share it with anyone.
4. If you see an error, stop and save it
Do not delete an installed eSIM or keep trying the code on different phones. If the eSIM is already installed but has no internet, use the “Installed but no connection” option.

5. Send us the error and phone model
Reply in the support form on your order page with your phone make and model, the exact error text, and the screenshot.
