Quick fixes

No data after installing the eSIM
Open Settings → Cellular, make sure the Siima line is turned on and selected for Cellular Data, and that Data Roaming is enabled for that line. Then restart the phone. Roaming must stay on — the eSIM connects to a partner network, so with roaming off it will show no service.
The QR code will not scan or says it is invalid
Each profile can only be installed once, so a code that already worked will fail on a second attempt. If this is the first install, use manual entry instead: Settings → Cellular → Add eSIM → Enter Details Manually, and copy the SM-DP+ address and activation code from your confirmation email or your dashboard.
Data stopped working mid-trip
Check your remaining balance in the dashboard — plans stop when the data allowance or the validity period runs out. If you still have data left, toggle Airplane Mode on and off to force a fresh network registration, or select a different network manually under Settings → Cellular → Network Selection.
I did not receive my confirmation email
Check the spam and promotions folders first. Your eSIM is always available in your dashboard regardless of email — sign in with the address you used at checkout. If you checked out as a guest, use the claim link from the purchase confirmation screen.
