I switched from Tesco Mobile to O2 in July looking for a better deal. I went with O2 as I know Tesco use their network and coverage had always been good with them.
Since switching signal has been poor for calls and 4G. I don't know if coincidence or not. Coverage checker is saying problem with a mast in my area, but would that cause problems for over 2 months? Really regretting moving but wondering if would now have problems with Tesco if I'd stayed with them.
