changing provider and pac code

[Ade74]

Hi,

i am wanting to change from a t-mobile rolling contract to the one plan on three. Normally i would just start a new contract and get a new number but this time i want to keep my number. Do i just have to ring t-mobile and ask for my pac code? Do they provide this straight away? Do i need to wait to get the pac code before i get the new contract from three?

Thanks both for replies. Not really bothered about contract overlap as i really just want my new phone. Will request PAC code from t-mobile then go into three shop and get new contract / phone.
