Welcome to the Community!
We were able to locate your account using your community details and the phone status shows that it is active.
Based on the call logs, you were able to dial out the number, but it wasn't answered. Could you please advise if you heard any error message when you call out? Have you tried to call your own mobile number to test if it's going to go through?
You may also try to turn off and on the modem to refresh the connection, then try to check the phone service again.
