freightliner_saxilby:I meant that I cannot move out of vodafone because I want to retain the same number and its a pain I am told to get a new number in a different company.
Who told you that? Vodafone?
To take your number with you when you change networks normally you just phone up your current network and ask for a PAC.
They might try to retain you and make you an offer. My advice is steer clear of a mobile phone contract, it's the easiest way to potentially scr*w your credit rating for 6 years for the least advantage. Look at each network's add-on options for one that suits your calling pattern.
Unfortunately if you have already bought a network locked phone you have made it difficult for yourself. Up to you, but try not to be conned.
