My phone works fine outside and has no problems however as soon as I get home it either has no network or network that then goes. It's done this before but normally when I'm at home it's fine. Whenever there's no network it keeps saying refreshing SIM data. I have put my SIM in another phone and it says the same thing. I know it's not my phone as I tried another SIM in there and it works fine
Are you saying you just have a problem with network coverage at home? In which case, is this a new thing or has it always been the case? Not much you can do with VM if it's always been that way, but you can check for known faults on EE (VM's host network) at https://myaccount.ee.co.uk/networkchecker/checkservice
Or are you saying you're getting error messages with your SIM card recently? You say about the problem following your SIM, this would indicate either a network or an account problem - although I'm still unclear on what your actual issue is.
