O2 communications black-out

Telegraph_Sam

I got the website to load on another PC in the end so it must be something to do with (the AV on?) this one. 
I suppose that somewhere (?) in the FAQ's there is guidance on switching SIM's within O2 but really I want to duplicate the SIM for safety in case for any reason one of the phones doesn't work.
I believe that there's a way for telling whether your contacts are saved to the phone or SIM (or both?) but I wasn't paying enough attention when the mobile shop was doing this for me last time. And how to copy them over.
I was surprised that your son was able to get through at all since all my attempts have failed.  But they always ask for a brief reason for the call at the outset and perhaps cancelling a contract was deemed a greater priority than .......ing about with a SIM card so I was screened out. Must be a lesson in there somewhere.

A quick google search:

Doro 409 manual with how to copy / storage of contacts.
From the next page it seems phone is default storage for contacts.
Instructions on how to copy from phone to sim on the linked page.
