I have an account with Three that I use in an iPhone 7, the signal dropped about a week ago and continually says "Searching", I took it into a Three store today and they swapped the SIM to a new one which does the same.
They said it's due to three changing their 3g signal, although the phone does show 4g in the network settings and "should" work, it doesn't.
Has anyone had any success using an iPhone 7 since Three dropped the 3g network?
