I’m using the 4G LTE base hat with the Quectel EC25 and I am able to access the internet. I want to try sending SMS messages next but have run into some trouble. I can communicate over minicom and the following AT commands return no errors but I never receive the messages.
AT+CMGF=1
OK
AT+CSCS=“GSM”
OK
AT+CMGW=“1530966XXXX”
+CMGW: 4
OK
What other information can I provide to help narrow down the issue?
