I’m unable to send SMS form my device. I checked and the Service Center Number (commonly stored in SIM cards) appears to be black. What is the correct address (number) to the Service Center to handle this request?
I asked to see what the number was it showed blank, I expected something like this:
AT+CSCA?
+CSCA: “+85291111111”,145
OK
And it is changed like this:
AT+CSCA="+85290000000",145
OK
