I got a card , GPS localisation is working but I cannot send an SMS.
AT+CFUN=1
OK
AT+CPIN=0000
ERROR
AT+CPIN?

AT+CBAND=“ALL_BAND”
OK
AT+CMGF=1

AT+CREG=1
OK
AT+CMEE = 2
OK
AT+CSCA?
+CME ERROR: SIM not inserted
AT + CMGS = “+324xxxxxxxx”
+CME ERROR: SIM not inserted
Battery is 1500mAh with 3.8Volt
Also, I check my SIM card on a MKR 1400 GSM and it works fine (can send SMS)
Any idea? Hardware problem?
Many thnaks,
Phil58
I’m sorry to ask an obvious question… do you have a service provider SIM installed for the SMS text?
I use the SIM card yet in MKR 1400 GSM to send SMS and works perfectly.
If card is not recognized, I suspect an hardware problem 
Thanks,
Phil.
Hello, If you have a basic sketch just to test the SIM card, I can load it and send you a feedback…
Thanks
@Phil58 I honestly do not have any experience with that device. I’m not sure a sketch will help if you’re receiving “+CME ERROR: SIM not inserted”… it seems like a hardware issue or conflict with your SIM (which obviously works in your MKR board). Did you have to assemble the board? If so, do you have any solder that may be touching header pins?

No, the board in not assembled for the moment, I just test it before to continue… but not work
