For about a week, I haven't been able to make/receive calls. The few calls that come through have such poor quality that they aren't functional.
I am in the US (Philadelphia) on a pre-paid unlimited plan that I've been on since 2011. My phone is a Panasonic Lumix CM1 (Android 5.0.2). My phone shows full bars and LTE coverage. Text and Data are as fast as ever - absolutely great.
When I attempt to make a call, it will say "Dialing" for 20-30 seconds and then "Call Ended", without ever going to a dialtone. We can use my husband's phone (he is on the same plan) next to me and his works fine. I have tried making calls from multiple locations and the problem exists everywhere. My sim card worked when I put it in my husband's phone and made a call using his phone. When someone calls me, the call goes straight to voicemail.
So far I have tried reseting the APN to default; having the Network Operator set to "Connect automatically", and doing a full factory restore on my phone. All without success in restoring my voice service.
My phone seems to recognize that the service is with T-Mobile and wants to connect, but it's just not allowing me to make/receive calls.
When I go to status it shows:
Signal Strength: -99dBm 42asu
Cellular Network Type: LTE
Service State: Voice: In Service / Data: In Service
Roaming: Not Roaming
Cellular network state: Connected
I've spent HOURS on the messenger with agents, and now they are telling me they can't help me because I'm on a prepaid account. They called me and connected me to 611 tech support, but the call quality was so terrible, 611 disconnected the call and now they are not answering my messages in the T-Mobile messenger. I don't have another phone available to call them and won't until Tuesday.
Can someone please help me to get my voice service back?
