Question: is 2g available in nz?
Answer: Once Vodafone and 2degrees' 2G voice networks close it will not be possible to use a 2G mobile phone with any New Zealand Sim card, meaning they will become useless. Spark does not have a 2G network. It adopted 3G as its minimum standard when it switched off its CDMA network and launched its XT mobile network in 2009.
