5G transit keeps restarting modem in a loop. AT&T card. Multiple firmware versions tried.
We are trying to help in the ticket. By the way, have you moved the AT&T SIM card to another cellular router/phone to test? Manage to connect? We need rule out whether it is related to SIM card or the SIM plan. The SIM card may tie to a IMEI or the SIM plan doesn’t work with the commercial router. This can be verified with AT&T.
Please help to rule out the problem and follow up with us in the ticket. Thanks.
