I don't know about port in, but sim card and the delivery is free. The card itself during the order, either you prefer to choose your number and what plan or you just order blank card and choose the number and plan later.
Just to remind that mnp approval might not so smooth depending on which telcos you want to port out. I have read some few complaints from their community forum.
Another thing, to have your number activated, debit/credit card is a must as they don't have any other payment options yet. This part a bit tricky as we need to call the bank first to enable the e-commerce function.

I just port in two numbers. No cost for 3 days delivery.

Once received sim card just active it and select what u want.

need to pay to activate?
