New Zealand uses GSM 2G 900/1800 3G 850, 3G 900/2100 AFAIK NZ is in the process of phasing out their aging CDMA networks as is many other carriers around the world.
There is no such thing as GSM gateway fraud. It is the cell phone carriers who are calling it as a gateway fraud. There is a gadget that is called a GSM gateway, which is basically a cellphone (GSM module), that can connect to the internet. What it does is to help you save international long distance calls, by using the internet. Of course the cell phone carriers are not happy about it since they can no longer earn money from your international long distance calls. That is why cell phone carriers will say that it is a "GSM gateway fraud". If it is true that GSM gateway calls are fraud, then internet is also a fraud, VOIP calls are also fraud, since they bypassed the international gateways of local carriers, that includes cell phone carrier and PSTN carriers.

Scientifically it is proved that The higher you go in the GSM number, the lesser the wavelength. Therefore GSM900 Is preferred than Gsm1800. But 3G uses 2100 what is the reason?
900 to 1800MHz
No. Okinawa has no GSM carriers, only CDMA.
In the US they most certainly do, as do all GSM carriers in the US.
Not all 3G networks use 2100 MHz, only 3G in Japan and South Korea does. The higher you go in GSM, the more superior the results, which means a GSM 1800 is better than a GSM 900.
gsm 900
Hi, For every GSM band there are Uplink and downlink frequencies. Example: GSM 900 TX: 880 MHz to 915 MHz is an uplink frequency range GSM 900 RX: 925 MHz to 960 MHz is a downlink frequency range Aloha, Maverick
GSM 900 possibly 1800 in big cities maybe even umts 2100 It is 900/1800 Mhz, source voltageplugregion.com /900/1800/2100(3g)/2300(4g)
