I will add my "case" as an extension of the problem. Perhaps there is a common denominator.
Play network, several numbers, different phone models, two different clients, so it's not just one affliction. Prepaid SIM cards though.
Incoming traffic:
Someone is trying to call me. He's been quiet for a long time. Then he gets "number busy". I have nothing.
Caller second attempt. He immediately gets a voice message in the style - "subscriber is on a call". I do not quote precisely, because only from the testimony. Nothing on my phone.
The phone is still registered on the network. Sometimes native, sometimes roaming T-mobile. Range "on the dashes" 4-5.
A moment later, I receive an SMS with the content "During the conversation, the user of this number tried to call you. The last call took place on ...., at..."
I wasn't having the conversation.
Now my outgoing traffic sometimes looks like this:
I dial the number from the book, the green handset ... I see the inscription "connecting..." and wait for 6-10 seconds and nothing. Then either I get a slow signal or the application gives up making the call.
Second try, third try, sometimes it works, sometimes it doesn't.
The condition is not regularly repeated. But it occurs frequently, at different times of the day.
I am usually about 300-400m from BTS.
Can I diagnose something on my side, or is the operator running out of its own network resources? ... and it's supposed to be like that?
