When I am in Europe (in countries which are supposed to have free roaming) I cannot use roaming services. On returning to the UK,  iD say that the problem cannot be diagnosed until it happens abroad! Since by definition I cannot contact them when it occurs abroad, I am in a Catch 22. This has happened in different roaming partner countries on different trips.

I have just got a new SIM card but Currys tell me that there is no guarantee that this will cure the problem. Has anyone else had this problem please?  I am thinking of leaving iD if another provider can give me some guarantee.
