I'm returning back to NZ in a couple of weeks and looking to pre-arrange as much as possible. I'd like to have sim cards waiting for my partner and myself the day we land as I have lots to arrange the first couple of days and not having to get to a spark store is a bonus if I can avoid it.

I'd like to buy prepay sims online now and have them delivered to my parents address - a couple of questions:

• Will the bundled ($19 packs) kick off only when I activate the sim?
• Will I know the phone number of the sims at checkout, or will they be in the physical package including the sim?

Hopefully I've not asked a redundant question - search seems broken (?) - much appreciated.
