Checked coverage and for RG7 postcode, it does give possible problems indoors for calls. Have now got to stage where I have to remove phone from case to make and receive calls. Even then often drop calls.
Even tried using calls over Wi Fi, no noticeable difference and I am on Virgin fibre high speed. Wife is on vodafone and does not have same problem.
So is if 3 (I am with ID) - seems likely as they admit problems indoor for calls. Or possibly phone (samsung A71), I will not pay for signal booster. so any other choices besides moving supplier?
