You've landed, everyone else is posting selfies, and you've got nothing. Run through this list in order.
- Is the kimsim line on? Settings → Mobile Service (Android: SIMs) → kimsim → turned on.
- Is Data Roaming on for the kimsim line? This is the big one. How.
- Is kimsim your mobile data line? How.
- Restart the phone. Fully off, 10 seconds, back on.
- Airplane Mode on for 30 seconds, then off. That makes the phone search for networks again.
- Give it a few minutes. The very first connection can take a little while, especially just after landing.
- Set the APN if data still doesn't start. How.
Bars but no internet?
That's nearly always the APN or the mobile data line. See steps 3 and 7.
Still nothing?
Don't delete the eSIM. Talk to a human and include your order number. We'll check the eSIM with the network. If we can't get it working, you get a full refund (activation guarantee).
