I am thinking of buying a new handset and have been doing a bit of research. According to the NZ Connections Wiki, only Vodafone currently offer GSM services in NZ; but NZ Communications, Orcon and Compass all have GSM services coming in 2008. In addition, I understand that Telecom are currently deploying a GSM/WCDMA network.
Basically, I want a handset that would let me simply switch SIM cards to change to another service provider. My understanding is that a quad-band GSM handset will work any of the providers mentioned above. Is this correct? Will a 3G capable handset work on Vodafone's 3G network and Telecom's new 3G network?
Do Vodafone NZ lock their handsets? (Or do they plan to lock them in future?) i.e. If I bought a handset from Vodafone NZ, will they be able to prevent me inserting a Telecom or NZ Communications SIM and using it on these new networks?
If I buy a parallel imported handset and insert a current vodafone SIM card, will the phone have the same functionality as if I had bought the handset from Vodafone NZ? i.e. would mobile TV, video calling and all other services work (assuming it was a 3G capable handset)? If not, is there any way to get around this?
Can anyone recommend a good handset for around $300?
