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" ERROR AT+CPMS="ME","ME","ME" ERROR AT+CPMS="MT","MT","MT" ERROR AT+CPMS="SM","ME","MT" ERROR
Please let me know if you have any solution.
