Installing your eSIM, start to finish

No physical card, no store counter. This walks through checking your phone, scanning the code, and the two settings that actually make data work once you land.

01

Check compatibility

Most phones from the last few years support eSIM. Confirm yours does before buying a plan.

Install the eSIM

The menu wording differs slightly by device. The sequence is the same either way.

After installing

Three settings account for almost every "it’s not working" message.

  1. A

    Data roaming is on, specifically for this eSIM

    It’s a separate toggle from your main SIM’s roaming setting, so switching one on doesn’t switch on the other.

  2. B

    The eSIM is set as your data line

    If your phone still points mobile data at your old SIM, data won’t move over on its own. Set it manually.

  3. C

    You installed early, activated on arrival

    Scanning the code any time after purchase is fine. Most plans start their validity countdown only once they connect to a network for the first time.
