We had an established LTE connection with AT&T but when we powered up again the next day the status remains in disconnect
Here is what we have tried and observe:
I verified the AT&T account is still active
I have removed and reinserted the SIM and rebooted several times with no success
I can scan and see operators but cannot register to a selected operator when trying a manual connection
I updated to the latest firmware from 1.14 to 1.14.3 but this did not resolve issue
I do have the trouble shooting log for review
I am looking for recommendations on what else I can try
