- Check the SAIMING line is switched on. iPhone: Settings → Cellular. Android: SIM manager.
- Check data roaming is on for the SAIMING line. It is off by default on many phones.
- Check the SAIMING line is selected for mobile data, not just switched on.
- Toggle flight mode on, wait ten seconds, and turn it off. This forces a fresh network search.
- Restart the phone. Modem state after a long flight is frequently the whole problem.
- Select a network manually. iPhone: Settings → Cellular → the SAIMING line → Network Selection → turn off Automatic and pick a local operator. Android: SIMs → the SAIMING line → Choose network automatically → off.
If manual selection shows local networks but none of them will register, try a different one before concluding the plan is faulty. Not every local operator is a roaming partner in every country.
Still nothing after all six
Message us with your order number and the country you are in. We can query the eSIM’s status with the supplier and tell you whether it is attached to a network — that answer is not visible from your phone.
