    I have a nokia lumia 1020 that is locked to Vodafone. I have a Vodafone sim so no problems with network there, I live in the UK. It happens more than once a day and occurs randomly (both using it and leaving it idle). It comes up with sim card error, invalid sim. Turning the phone on and off sometimes helps but not always.

    Can someone please help as this is quite annoying, thanks.

    Speak to the network operator and get them to send you a valid sim
