As of yesterday my phone was okay as I know I had a missed call and checked it on voicemail, but today I noticed that it is showing no signal when there should be one.
The last thing I know I did was to try *#61# to check the voicemail numbers as I was thinking of setting a longer timeout, but I didn't actually change it.
If I go into Additional call settings I get 'Network or SIM card error', but I expect that is linked to the lack of network. However, I wonder if something on the SIM is messed up.
I've turned it off/on a couple of times. Also tried a different SIM from a different service and that worked. It there anything I can try resetting?
