Use this commands to check the status of the module AT+CCID - getting a SIM card number AT+CSQ - signal quality: 0 -115 dBm or less, 1 - 111 dBm, 2-30 -110..-54 dBm, 31 -52 dBm or more, 99 -unknown or no signal.

AT+CPAS - module status: 0 - ready to work, 2 - unknown (command execution is not guaranteed), 3 - incoming call, 4 - voice connection "AT+CPAS" will tell you, is the module ready for calls or is it having problems

thanks for quick reply, I get sim card number, CSQ usually gives me something like 26 CPAS gives 0 after a while when network light flashes slower

When i try ATD command i get either NO CARRIER or NO DIAL TONE

does the simcard have to be 2g only?

Also I made a Companion app by forking the UART terminal app and made specific slots for not having to type every command and im still working on it.

Hmm, that's interesting. I have a "NO DIAL TONE" error if AT+CPAS was giving out "2". I tried SIM cards from different providers, the calls went through

I put a star and signed up, great job
