I am currently using a Mate 20 Pro for almost 4 months, and just last Friday it stopped receiving calls and texts. I just thought to myself, "maybe no one was texting me at all", and got the feeling there's something wrong so upon trying to text myself, I cannot send any messages at all. I tried borrowing a phone to both call and text my own number, and still not receiving any, saying my number is "unavailable".
Weird thing is, it only happened out of nowhere, while my phone is on my desk while at work. Also, the data feature seems to work fine, just calls and texts are not working.
Troubleshooting steps performed:
Reset network settings - same issue
Cleared cache/data from both Dialer and Messages app - same thing
Factory reset phone - still not receiving texts or calls
Used sim card/s on a different phone - works perfectly fine
Had carrier replace sim card/s - still no issues when inserted on a different phone
Any ideas on how to resolve this issue guys? I'm getting frustrated as it is now 5 days since I started troubleshooting this issue
