Can not get IMSI and IMEI with AT commands

I am using a raspberry pi to communicate with an SL8092 modem from Sierra. I am able to communicate with the device via the /dev/ttyUSB4 using minicom.

Sending AT commands returns the following answers:

> AT
< OK
> AT+CSQ
< +CSQ: 30,99
>AT+COPS
<+COPS: 2

But when sending AT+CIMI or AT+CGSN, I am expecting to get the IMSI and the IMEI. Unfortunately it's not the case - the only answer I get is just "OK".

Am I missing something?

You can try using these AT commands and find out which are valid with your device. This is for the phone so I am not sure it works with your Pi.

  • API
  • AT+IMEINUM
  • AT+DEVCONINFO
  • AT%IMEI?

You can find out some useful AT commands here: https://atcommands.org/atdb/

From document:

!GRELIMEI

Return the modem’s production TAC (Type Allocation Code).

(TAC is first 8 characters,then padded with zeroes).

For example, if IMEI is 289258158732085, the TAC is 289258150000000.

Usage:

  • Query: AT!GRELIMEI?
  • Response: [TAC] OK
  • Purpose: Return the [TAC] assigned to the modem.
  • Parameters: [TAC] 15-character string. (TAC is the first 8 characters, and remainder of string is zeropadded.)

Example: If the modem’s IMEI is 289258158732085, !GRELIMEI returns 289258150000000.
