An eSIM is a SIM card written into your phone's hardware. There is nothing to post,
nothing to cut, and nothing to lose. Installing one takes about two minutes on Wi-Fi.
Before you start
- Check that your phone is eSIM capable and carrier-unlocked.
- Stay on Wi-Fi during installation.
- Keep the QR code from your order email — you may need it if you change phones.
iPhone
- Open Settings → Mobile Service → Add eSIM.
- Tap Use QR Code and scan the code from your confirmation email.
- Label the plan (for example "Travel") so you can tell it apart from your home line.
- Set your home SIM as the default voice line and the new eSIM as your mobile data
line. - Switch Data Roaming on for the eSIM only.
Android
Menu names vary slightly by manufacturer.
- Open Settings → Network & internet → SIMs → Add eSIM.
- Scan the QR code, then confirm the download.
- Enable the profile and select it for mobile data.
- Turn on roaming for that profile.
When does the plan start?
Validity begins when the eSIM first connects to a network in your destination — not
when you install it. So you can safely set everything up days before departure.
Troubleshooting
"Unable to add eSIM" — you are usually offline or behind a restrictive Wi-Fi
network. Try mobile data or another network.
No signal after landing — toggle flight mode, then pick the operator manually.
Some networks need up to five minutes on the first attach.
Data does not work but the signal is there — check that the eSIM is selected as the
data line and that roaming is enabled for it.
QR code already used — an eSIM profile can only be installed once. If you deleted
it, contact support and we will reissue it.
