I don't seem to be able to reliably make a phone call anymore unless I am stationary. It's utterly ridiculous and seems to have gotten significantly worse in recent years. My husband works on an industrial estate but I can't speak to him when he is there as he gets no signal, it's a bloody business park! We do live relatively rurally but no matter what direction I drive, I can't make any kind of call (obviously through my car). I used to be able to use my commute time to catch up with people but it is too painful now and I don't bother.
Apparently this is down to the switch off from 2G but why are we paying more when it's so unreliable?
