Dear All

I face a problem related  to apply calling using AT command through GSM modem as below:


Model:
AT+CGMM = E355s-1
Manufacturer:
AT+CGMI= Huawei

When I use (ATD+963*********;) I get (No Career), also when try to call the number who inside the Modem will  display as busy without any reflection on interface of Modem or Putty.



Thank you.

Hello, dear.
GSM-R belongs to railway communication. The question about the E355S-1 demodulator you asked does not belong to the products included in the enterprise wireless, and I have not found the relevant information package. As far as I know, the AT command format is AT+command, there is no ATD+number format.

I suggest clearing the registers with ATZ before the call, if allowed, usually ATZ&ATDxxxxxx. I hope to help.
