Do any of the mobile phone suppliers do deals for bill pay if you have 2 or 3 phones on the one contract. I know they do deals for business but but are there any for families?
I don't know to be honest but I would certainly email them and ask as they are all anxious to retain customers or maybe better still if you ask through their forums, both O2 and Meteor have them not sure about Vodaphone.
or 3.
