How do you change your network?

i am currently on orange but i want to change to 02 because they have better deals.. is there a way i can do this?How do you change your network?
personally i think that t-mobile has the best deals but you might want to try buying a new simcard thats with o2How do you change your network?
Yes. Firstly get your phone unlocked. (cost about 拢10.00). Then purchase an 02 simcard (cost about 79p from a pound shop). Then phone up orange request a PAC code (they may offer you all kinds of deals i warn you now ;so be prepared for them to be obstructive.) once you have the PAC code contact orange and quote it to them. You should be up and running once you've topped up with 02. hope this helps.
