Your neighbourcell results show cells on B3 and B40.

Your servingcell result indicates that you’re camped on a B3 cell for emergency use only. That’s MCC=405 (India).

Is your APN Hughes1.com correct?

What provider’s SIM are you using? Is the APN correct for that provider?

What does the AT command AT+COPS=? return? It can take a minute or more for that command to return a result?

What are the left-most six digits of your IMSI? The AT+CIMI command should return your SIM’s IMSI.

If the modem can’t read the SIM, have you tried carefully cleaning the SIM and Modem contacts.
