Suffered sudden long drops in text/phone signal ever since. 3G also occasionally went. Resetting phone brings everything back for hour or so. Have not re-updated carrier settings.<BR />Spoke with o2 who advised this may be because I had cellular set to 4G (wasn't aware this wasn't supported) so reset network settings and changed to 3G. Again signal began to drop.<BR />O2 sent a simswap which I did 24H ago and again both signals (mainly text/call) are still dropping.<BR />Any ideas anyone?
