nigelj:solaybro: What do I need to look for when buying a phone? To my understanding some don't work in NZ.
I was looking at this one http://www.kogan.com/nz/buy/samsung-galaxy-s4-mini-duos-i9192-white/
General rule of thumb (n.b. this does NOT apply to 4G services/phones) is, if it's advertised as compatible with Telstra 'Next-G' (I think that is what they used to call it) or Vodafone AU, then it supports 850MHz 3G and will work on Telecom NZ (and it's MVNOs), if it's advertised as compatible with Optus/Virgin/etc then it typically operates on the 900MHz 3G and is better fitted towards Vodafone NZ/2degrees.
From the 'Specs' tab:2G Network (MHz)850 / 900 / 1800 / 19003G Network (MHz)850 / 900 / 1900 / 2100
It'd appear that it's quad-band and would work on all 3 NZ networks. Anyone else on similar view?
What do I need to look for when looking at 4G phones, I found another phone that is 4G LTE.
It's out of stock but here it is: http://www.kogan.com/nz/buy/samsung-galaxy-s4-mini--4g-lte-i9195-white/
