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.

2G technology, which refers to the second generation of mobile telecommunications, was developed in the 1980s, with significant contributions from various organizations and researchers. Notably, the GSM (Global System for Mobile Communications) standard, which became a key part of 2G, was developed by the European Telecommunications Standards Institute (ETSI) in 1982. The first commercial 2G network was launched in 1991 in Finland by Radiolinja, using GSM technology.
No . Samsung Wave 525 is not a 3G mobile but is a 2G mobile. It has 2G Network :GSM 850,900,1800 and 1900
GSM Band 890 to 915= 25 MHz One GSM Channel BW= 200 KHz Total GSM channels=25MHz/200KHz=125
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
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.
Yes, Edge is faster than GSM. Edge offers data speeds of up to 384 Kbps, while GSM typically supports slower data speeds ranging from 40-100 Kbps. Edge is a 2G technology that provides faster data transfer rates compared to traditional GSM.
The full name of GSM is "Global System for Mobile Communications." It is a standard developed to describe protocols for second-generation (2G) digital cellular networks used by mobile phones. Originally developed in Europe, GSM is now widely used around the world for mobile communication.
