O2 to O2 switch?

[SP83]

Is it possible to keep my current O2 number if I buy a new phone with a new contract, but still with O2? I am due an upgrade but there is a brilliant deal out there at the moment (not buying directly with O2) that is simply too good to miss and I can't get anything anywhere near as good by just upgrading.

Thank you!

@SP83 Yes, just call 202 when you get your new contract and they will migrate your number.

@MI5 is (as usual) correct @BigDaddyUK and @SP83.
I have done it (moved my number from one o2 contract to another) twice now.
Both times the deal I had from another company was better than the ones available from o2 directly (so long as a 2 year contract was not an issue).
So long as your current deal (or the minimum period, or the handset payments) has finished, once you have the new handset/SIM just call customer services and ask them to move it.
Takes 24 hours or so (depending on when you ask them) but closes the old contract and moves the number.
As the meerkat says, simples!
