Hi, I am having problems with my phone after the latest update, my phone will not read sim cards, I replaced my sim card via vodafone to confirm wasn't sim problem , still wouldn't read. I then tried my sim in another phone and it works fine. I have tried a sim from another network and this is the same. It is either no service or signal bars and emergency calls only no matter where I am. I have factory reset the phone. I have tried airplane mode of and on, Manually selecting network operators this sorts problem for a few minutes sometimes, tried clearing cache everything that I could find online.
@Joek1975: Further to the post by @Pugs1957, please head to Settings > Connections > Mobile Networks > Access Point Names to check your existing settings. You may also wish to try tapping the 3 dots in the top right > Reset To Defaults, to see if this helps. Tap the Back button > Network Operators > Select Automatically > On. Go back to the Connection settings screen > SIM Card Manager, and make sure that the relevant SIM is toggled on at the top of the screen.
