Like in the topic, I can not connect to any mobile network. Factory reset did not help, turning off the phone for half an hour does not help like it was advised in numerous topics. The things I have not tried yet is configuring manually the apn settings.
All of this started when I have changed my battery. because the previous one I had went completely dead after swelling like a little airbag. My replacement battery I have is also branded by lg and is the same model, like the previous one was.
My simcard is a one distributed by polish t-mobile and if there is like a localization issue, I am not able to go to poland now because I live in wales at the moment.
