Installing your eSIM
Does my phone support it?
Two things have to be true:
- eSIM capable. iPhone XS or newer; most Android flagships from 2020 on.
- Carrier unlocked. A phone still locked to the network you bought it from will refuse a second profile.
On iPhone: Settings → General → About, and look for "Available SIM" or an EID. On Android: Settings → About phone → look for an EID. No EID means no eSIM.
One tap, on the phone itself
The quickest route needs no codes at all. Open your order page on the phone that is travelling and press Install on iOS or Install on Android: the profile is handed straight to your phone's own eSIM setup, and all you do is confirm. Needs iOS 17.4 or Android 10 and later.
Buying on a laptop instead? The same page shows a QR code — that is what the steps below are for.
iPhone, by QR code
- Settings → Cellular (or Mobile Service) → Add eSIM.
- Choose "Use QR Code" and point the camera at the code on your order page.
- Label it something you will recognise — "Clear Roam Japan" — and leave your usual SIM as the default line for calls and messages.
- When you arrive: Settings → Cellular → select the Clear Roam line → turn on Data Roaming. That switch is what makes the plan work, and it does not cost extra.
Android, by QR code
- Settings → Network & internet → SIMs → Add eSIM (wording varies by manufacturer).
- Scan the QR code from your order page.
- When you arrive, enable the Clear Roam SIM and turn on roaming for it.
Entering it by hand
If the camera will not read the code, every order page also shows the two fields it contains. Choose "Enter details manually" and type the SM-DP+ address into the server field and the activation code into the code field. Both are case-sensitive.
Still stuck?
Email [email protected] with the address of your order page. An eSIM you have not installed can be refunded; one that has already connected to a network cannot, because the data has been bought from the carrier by then.
