All day I have been having problems with service and network connections, I had 2 hours of my phone saying no service I tried turning it off and on I tried manually selecting a network and searching for a provider and nothing, I tried different locations for service aswell as the network tracker on the app and everything was fine, every now and then I’ll get about half and hour to an hour of service before it cuts out again and I don’t know if it’s my phone being faulty or my sim or if there is a problem with o2 itself... any help would be appreciated
