I am trying to set the memory location of my phone (Nokia 2730 Classic) but I am not able to set the storage location. I have also tried with the 7 port multi sim card hub and got same issue there as well. I am using the Ubuntu system and using Minicom and Screen command to connect serial port. When I tried to send SMS from the device using AT command it is working fine but the reading of SMS is not working due to storage location is not set.

While I am trying to execute command AT+CPMS I got below results.

AT+CPMS?                                                                        
+CPMS: ,,,,,,,,                                                                 

OK            

AT+CPMS=?                                                                       
+CPMS: (),(),()                                                                 

OK

And when I try to set the location of storage using below commands then getting errors.

AT+CPMS="SM","SM","SM"

AT+CPMS="ME","ME","ME"

AT+CPMS="MT","MT","MT"

AT+CPMS="SM","ME","MT"

Please let me know if you have any solution.

Thanks

  • It seems a bug a bug of your device. Are you sure that it communicates correcly with the SIM card? – Roberto Caboni Mar 26 '20 at 11:49
  • For example: is the PIN correctly inserted? – Roberto Caboni Mar 26 '20 at 14:34
  • @RobertoCaboni yes it is communicating with the sim. I am able to send SMS through AT command but while I am trying to read SMS it gives the error. So I checked the storage preference and while I run AT+CPMS at that time it shows output like above and if I am trying to set AT+CPMS="SM" then also it's giving an error. – Nicole Mar 29 '20 at 03:25
