Hello! Here's a detailed description of my issue: 1.
Here's a detailed description of my issue:
1. 4G works, text works, but not phone calls (receiving neither calling); if someone calls I'm offline for him
2. After any attempt to call, the connection is either lost -offline- or connected but with lost data download/upload for a minute
3. Phone calls worked only for once (received)
Tried switching sim to 2nd trey (dual sim device) with no success; I also tried resetting configuration files with same result
What could be the problem? What do you suggest?
Thank you in advanced...
