PAC code needed for purchase?

in the uk, it is later

 

with cpw it has to be at the time of the order but with o2 i think you can do it later

 

From what I remember from the previous iPhone, it asked for a pac when you activiated it in iTunes. I already had it so I don't remember if there were options to wait. I've got a feeling that if you want to keep your number this has to be sorted out from the start, it's not something you can do afterwards. But don't quote me. Someone on here will know better.

Anyway, as the pac is valid for 30 days I'd go ahead and get it. Nothing happens if you don't use it.

 

In the UK both orange and vodafone post it to you, take five working days or so. I spoke to O2 yesterday though and they said that you can phone them up with the PAC code one you have a contract setup and they will port the number across in a couple of days.

Handily it normally happens instantly, i.e once the number leaves your current network it appears on the new one strait away. Though last time i ported i could ring from both phones for about an hour which was confusing.
