I got my phone in June 2020, I have had poor mobile signal since then. Over the past 2 months it’s has been particularly bad. I can’t get through any of my phone calls without the signal breaking up or cutting out completely. When I am at work in certain parts of the building I lose signal and 4G connection completely. It is some of the worst signal I have ever had.
Also it’s as though my phone believes it it registered in another country. I have checked settings and it is registered in United Kingdom. Sometimes numbers appear broken up (in pairs) and they can’t be dialled. I was told to turn dial assist off. I have checked my settings and it is still off and this still happens. Any help would be great please.
