using on Samsung phone with Android 9.0 Messaging application version 24.01.1502.1021
I have 1GB SIM with Phone number XXX-XXX-1230. I have setup the APN etc properly and can use the data. For some reasons I can't make any calls or receive calls. When initiate a call, the application shows calling, but no sound and receiver doesn't receive the call. When other person calls my number, i don't get any ring or indication, but when they hangup I see missed calls notiification.
