SMS and calls no longer working

[Thanos]

I got my PinePhone community edition a couple weeks ago, but last week I stooped being able to send or recieve calls and SMS messages. I tried sending the AT commands directly to the modem but both commands returned errors. ATD returned “NO CARRIER”, and AT+CMGS returns CMS error 350, which is completely undocumented. Mobile data still works perfectly and there is nothing to suggest an issue with the service to the device. I’m not really sure what to do from here. I have a feeling that it might be an issue with the way the modem is configured but I’m not sure if factory resetting the modem will break anything.

Hello!

Can we have more information of which version you’re using? Is it factory image? stable? unstable? etc?
Or did you flash another ‘Phosh’, ‘Lomiri’ or ‘Plasma Mobile’?

Did you update the PinePhone?

Also, do you know if you’re SIM card is compatible with PinePhone?

I’m using the factory image. I have kept it up to date, but the issue did not coincide with an update. and my sim is compatible. I should mention that I’m using verizon.

I did a quick search and found this, might help or not… also from what I read it seems commons to get that error.

(Did you try a reboot of the phone each time you get it?)

Also it seems this could do the documentation : SMS Tutorial: Result Codes of AT Commands. The OK and ERROR Final Result Codes

Hope it would help you, I don’t know if I can do more for your case…

AT+CUSD=1

Set command allows control of the Unstructured Supplementary Service Data (USSD > 3GPP TS 22.090 ).
0 - disable the result code presentation in the DTA
1 - enable the result code presentation in the DTA
2 - cancel an ongoing USSD session (not applicable to read command

AT+CPBS=“ON”

Set command selects phonebook memory storage , which will be used by other phonebook commands.
"ON" - SIM own numbers (MSISDNs) phonebook (+CPBF is not applicable for this storage).

AT+CPBR=1

Execution command returns phonebook entries in location number range .. from the current phonebook memory storage selected with +CPBS. If is omitted, only location is returned.

AT+CNUM returns the MSISDNs related to the subscriber.

But in many cases it will just return OK . This is because +CNUM command reads a special phone book storage area reserved for the SIM’s own phone numbers. The service provider may or may not store the phone number for you.

If you want to read the MSISDN with the +CNUM command and it is not currently programmed, follow the procedure below (but please know that almost every other device has it’s own set of rules for AT commands so it may vary from device to device, but the concept will be same): at+cnum?

+CME ERROR: unknown

at+cpbs? - display the active phonebook storage

+CPBS: “SM”,250,250

OK

at+cpbs=ON - select the active phonebook storage to MSISDN list

OK

at+cpbs? - display the active phonebook storage,

+CPBS: “ON”,0,3 - MSISDN list is empty

OK

at+cpbw=,"+918723976327" - enter your own MSISDN

OK

at+cpbs? - display the active phonebook storage,

+CPBS: “ON”,1,3 - MSISDN list has one item

OK

at+cpbr=1 - reading MSISDN list, position 1

+CPBR: 1,"+918723976327",145,"" - own MSISDN

OK

at+cnum

+CNUM: ,"+918723976327",145 - own MSISDN

Hope this helps!
