Hi Jamal,

Here is the Step-by-Step Procedure.

1. Check SMS Storage

   • Ensure the SMS storage is set correctly (usually to SIM or ME):

     AT+CPMS?
     
     

     This returns the current storage settings for read, write, and received messages.

2. List Messages

   • To list all messages in the storage:

     AT+CMGL="ALL"
     
     

     Options include:

     • "REC UNREAD" → unread messages

     • "REC READ" → read messages

     • "ALL" → all messages

3. Read a Specific Message

   • Use the message index from the list:

     AT+CMGR=<index>
     
     

     Example:

     AT+CMGR=1
     
     

     This will return the message status, sender number, timestamp, and message text.

4. Delete Message (Optional)

   • After reading, you can delete the message:

     AT+CMGD=<index>
     
     

     Example:

     AT+CMGD=1
     
     

---

Important Notes

• SMS Mode: Ensure the module is in text mode for SMS:

  AT+CMGF=1
  
  

  (Use AT+CMGF=0 for PDU mode if needed.)

• Error Handling: If you see +CMS ERROR, check SIM status and network registration.

• ThreadX Specific: The commands above are standard 3GPP TS 27.005 compliant and supported by LE910Cx ThreadX firmware.
