There is no QR code at purchase. This is an activation booking. You add the eSIM after you land in the US, on the airport's free Wi-Fi — it cannot be set up before you leave.
Enter your arrival date, who will use the line, and the phone's EID / IMEI. No QR code is issued.

Before you buy
You need your EID and IMEI to order. Dial *#06# in the phone app to see both. If two IMEIs are shown, either one is fine.
We activate the line between 7 and 10 AM US Pacific Time on your arrival date. Your plan starts at activation.
Same-day activation is not possible — the earliest arrival date is tomorrow. Enter the date as the local US date.
Your phone must support eSIM and must not be carrier-locked.
AT&T works on iPhone only.
The line works inside the US only (some AT&T plans include Canada and Mexico).
If the EID or IMEI you entered is wrong, it can be corrected before activation — contact customer support (it cannot be changed after activation).
The plan length is counted as 30 days per month, starting on the activation date (e.g. a 1-month plan runs 30 days from activation).
You check your remaining data and minutes by dialing carrier codes on the US line after activation (the codes are in the activation email and on your order page). Usage cannot be shown on this site.
To extend your plan, contact us — or top up directly with T-Mobile / AT&T.
Once activated, the plan cannot be cancelled or refunded.
