Mobile Network Change :)...?

Hi all :)



Do any of you know how to change your mobile to a different network?

Currently, mine is on Orange, but I really want to change it to 02 because I've been with 02 for a very long time, and I'm very used to that network, rather than Orange.



My mobile type is: SGH-U900 (incase this information is needed for you guys to help me out, lol)



Thanks if any of you people answer this! :DMobile Network Change :)...?
If you mean take the number from orange to o2, then you will need to ring orange and get a pac code, when the pac code comes, give the pac code to o2 and they will move the number over.



If you mean use that phone with your o2 number, then you MAY have to get the phone unlocked,which can be anything from 拢10 to 拢50. If the phones unlocked then just take orange sim out and put the o2 sim in and that should be you ready to go.Mobile Network Change :)...?
If you have no form of contract with orange, it is relatively easy to switch, firstly you will need a o2 sim card, and to make sure your SGH U900 is unlocked to accept all networks(if supplied by orange may be locked to orange network and a small feee may be required to unlock it), once its unlocked all you need to do is insert you new o2 sim card registerit and your away, a good idea would be to ask Orange for whats know as a PAC ( porting authority code) when givin to o2 they should be able to transfer your exsisting orange mobile to yur new o2 sim card allowing you to retain the old number so you dont have to conntact everyone about the change in number.
