What PAC is for
PAC stands for Porting Authorisation Code. In plain English, it is what allows your old mobile number to move from your current network to your new one.
It does not create the referral discount and it does not replace the sign-up journey. It is a separate admin step that matters after you know you want the new plan.

When to request your PAC
For most people, the cleanest timing is to use the referral route, choose the plan, and confirm the discounted price before payment. Once you know you are happy to move, request the PAC and complete the number-transfer steps.
Common PAC confusion
- Thinking PAC has to be sorted before the initial order.
- Assuming PAC affects whether the referral discount shows.
- Cancelling the old SIM too early.
- Not planning for a short transfer window.
Common questions
PAC code FAQs
These are the questions people usually ask before they switch. If anything affects your decision, verify it during checkout or on the provider’s support pages before you pay.
Does PAC control whether the discount appears?
No. PAC is for moving your number. The referral saving is a separate checkout issue, so keep those two tasks separate in your mind.
Can I still keep my number if I use the referral route?
Yes, usually. The referral route gets the order started. PAC handles the later number-transfer part.
What is the most practical order?
Check coverage, sign up cleanly, confirm the discount before payment, then deal with PAC and the number transfer.
