The phone started losing network connection at my house and on my street. There is no coverage at all, both data and calls do not work.
I have tried the SIM in other phone and it works well, no one else at the house has this problem, so it must be the phone.
I have tried changing networks, manually reconnecting, restarting nothing helps. It connects on few hundreds meters from the house and works fine.
The phone was replaced in warranty, as the previous one was losing network everywhere. The new device worked fine for 6 months and then starting having problems.
Any suggestions on what to do next ?
