I cant make or receive call. Message says not registered to a network

@Catherine7 

Try rebooting your phone and check guides:

Guide: How can I sort out my network issues? 

Guide: Is the network down for me or everyone?

I called tech support yesterday morning with the same fault - apparently, there's a problem with the local cell mast and they are working on it.   You can check on the status of the fault here:  https://status.o2.co.uk/

@JosieB 

If that comment is meant for @Catherine7, you need to tag her thus. 

The possibility of a network fault is covered in the guides that @MI5 has referred to, but I am sure that @Catherine7 will want to fully explore that. 👍

@Oxonian Thanks,  I am new to this board and stupidly assumed that hitting the "reply" button would direct my response to the right place, my phone has just come back on so hopefully @Catherine7 is back online too.

You are welcome @JosieB. 

@Catherine7 is welcome to ask for further suggestions if her issue has not yet been resolved. 👍
