Hello, you were right, my SIM subscription does not allow sending SMS... So I tried with another SIM card (orange SIM card) and I managed at last to send SMS! Great! Thank you for your help every one.

I UPDATED THE LTE MODEM AND ALL WENT WELL...is this something that should be notified to the members? I want aware i could update it.

I had a wild stab-in-the-dark this avo import time, network lte=network.LTE() def _getlte(): if not lte.isattached(): print('lte attaching '); lte.attach() while 1: if lte.isattached(): print(' OK'); break print('. ', end=''); time.sleep(1) _getlte() print ('try sending an SMS') lte.send_at_cmd('At+CMGF=1') # put it into text mode? lte.send_at_cmd('AT+SQNSMSSEND=61xxxxxxxxx,This is the SMS content') # where 61xxxxxxxxx' is a mobile number A doesn't work bench mark to start from?

Finally! import time, network lte=network.LTE() def _getlte(): if not lte.isattached(): print('lte attaching '); lte.attach() while 1: if lte.isattached(): print(' OK'); break print('. ', end=''); time.sleep(1) _getlte() print('configuring for sms', end=' '); ans=lte.send_at_cmd('AT+CMGF=1').split('\r\n'); print(ans, end=' ') ans=lte.send_at_cmd('AT+CPMS="SM", "SM", "SM"').split('\r\n'); print(ans); print() print('receiving an sms', end=' '); ans=lte.send_at_cmd('AT+CMGL="all"').split('\r\n'); print(ans); print() print('sending an sms', end=' '); ans=lte.send_at_cmd('AT+SQNSMSSEND="61419123456", "This is the SMS content"').split('\r\n'); print(ans) gives configuring for sms ['', 'OK', ''] ['', '+CPMS: 6,30,6,30,6,30', '', 'OK', ''] receiving an sms ['', '+CMGL: 1,"REC READ","+61419123456",,"19/07/07,16:29:43+40"', 'C', 'Text to gpy test', 'OK', ''] sending an sms ['', '+SQNSMSSEND: ID,14', '', 'OK', ''] hope this saves someone some trial & error time.

@dan Any updates on this issue? Seems like their hasn't been much change in the documentation.

@jmarcelino ok, thx for this answer! Maybe i shoud introduce you into what my project is and you can tell me what the easiest way would be to implement this. In general i can say i want so send data from a Sensor to anywhere where i can catch the information from and i want so see it everywhere. This is what the IoT is for... ?. I don´t know realy much about programming, cellular network and internet protocols so my first idea was to send a sms or email. Now i know ist possible, but just with other providers or with detour. In my opinion it good to be independent as much as possible. I would like to use the internet via cellularnetwork . Thats why i chosed the GPY. The board can send from anywhere over LTE-NB-IoT. I hope in the near future i can put my sim-card inside the GPY and connect to the Internet. So this is the way i´ll send my data. Could this work?! :S But how to recieve and which transfer method would be good for sending via internet? Today i tried sending data with MQTT via WLAN. The example from https://www.hackster.io/bucknalla/mqtt-micropython-044e77 worked very good with my GPY! I also have seen that i can open my own MQTT-Server with https://mosquitto.org/ . Do you know: Would this also work with the LTE-module in the future? Is there a better solution you can recommend me? Maybe some thing with FTP- or MYSQL_Server(to heavy?)?! Thank you very much! Andy
