PAC after ordering

[#1]

Hi I’m getting a sim for my daughter at uni.
It says if I enter her pac the number will port 2 days after posting.

This doesn’t allow for postal delays or give me time to receive it and repost out to her before her old sim disconnects.

If we want to use the pac after, do we text it to a port number or something?
The order system seems to insist on having the pac when ordering if you want to transfer a number!

Thanks

Is there an option when ordering not to transfer a number? I’d select that if so then you can port it afterwards once you’ve received the SIM and sent it to your daughter.
