2G introduced data services for mobile like SMS text message wich is irrelevant of it being cdma/gsm.
The Nokia 6260 phone while it was produced worked on the GSM 900 / 1800 / 1900 2G Networks outside the United States and the GSM 850 / 1800 / 1900 2G Networks inside the U.S.

No . Samsung Wave 525 is not a 3G mobile but is a 2G mobile. It has 2G Network :GSM 850,900,1800 and 1900
Digital traffic channels - first g :purely analog 2g: systems are digital encryption: all 2g provide encryption to prevent eavesdropping error detection and correction: 2g traffic allows for detection and correction, giving clear voice reception channel access: 2g systems allow channels to be dynamically shared by a number of users
GSM Band 890 to 915= 25 MHz One GSM Channel BW= 200 KHz Total GSM channels=25MHz/200KHz=125
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.
Advantages of 2G GSM * GSM is mature; this maturity means a more stable network with robust features. * Less signal deterioration inside buildings. * Ability to use repeaters. * Talktime is generally higher in GSM phones due to the pulse nature of transmission. * The availability of Subscriber Identity Modules allows users to switch networks and handsets at will. * GSM covers virtually all parts of the world so international roaming is not a problem. [edit] Disadvantages of 2G GSM * Pulse nature of TDMA transmission used in 2G interferes with some electronics, especially certain audio amplifiers. 3G uses W-CDMA now. * Intellectual property is concentrated among a few industry participants, creating barriers to entry for new entrants and limiting competition among phone manufacturers. * GSM has a fixed maximum cell site range of 35 km, which is imposed by technical limitations.

You need one with a SIM Card slot. From there, find a GSM carrier, buy a SIM card and slip it in. (T-Mobile, AT&T, and every European carrier is GSM).
