(Hillingdon, Uxbridge) Since the 20th this month, my sim was working fine and I had strong signal, I have paid my phone bill but since Monday I've had no bars, also my phone telling me next to those bars that I have no sim. I've done all the troubleshooting I can to fix the issue and still nothing. I've used the service checker and I'm told a Mast hasn't been working properly and is being "fix" 3days I've had no bars or working sim (not able to use data) anyone from Hillingdon Uxbridge having the same issue?
