After switching to O2 my sim got inactive

[crazy_format]

After switching from Vodafone to O2 my sim card stopped working, now it cannot connect to the network and I cannot neither receive sms messages nor calls.

We’re just customers like you but it sounds like you’ll need someone to access your account which can’t be done from here. If you message O2 using the links below, they should be able to help you with this

or give them a call on 202  or 0344 809 0202
