JonC: So with their website saying "You'll be able to choose any Telecom mobile", does this mean that they're going to stop selling ones that aren't NP-compatible? Given the phone-list from nzbnw, this would narrow the phone selection somewhat...
[EDIT] Oh, I see, these are just the soft-launch ones - the rest are yet to be tested... So I guess if you've got a phone that's not currently for sale (from April 1) then it's not guaranteed to be NP-compatible?
From what I have heard all current handsets will be compatible, from licensed dealers and retailers. There is always going to be some limitations, such as with the Nokia 2355 not supporting 9 digit numbers which is regrettably unavoidable. Also handsets purchased from other sources such as trademe are not guaranteed to be compatible.
Hope this helps.
