The cell phones utilise UMTS in combination with 2G GSM standards and bandwidths, but do not support EDGE.The latter group is the UMTS family, which consists of standards developed for IMT-2000, as well as the independently developed standards DECT and Wi MAX, which were included because they fit the IMT-2000 definition.The communication spectrum between 400 MHz to 3 GHz was allocated for 3G.Both the government and communication companies approved the 3G standard.However, many services advertised as 3G provide higher speed than the minimum technical requirements for a 3G service.

3G telecommunication networks support services that provide an information transfer rate of at least 0.2 Mbit/s.A new generation of cellular standards has appeared approximately every tenth year since 1G systems were introduced in 1981/1982.Each generation is characterized by new frequency bands, higher data rates and non–backward-compatible transmission technology.The following standards are typically branded 3G: The above systems and radio interfaces are based on spread spectrum radio transmission technology.While the GSM EDGE standard ("2.9G"), DECT cordless phones and Mobile Wi MAX standards formally also fulfill the IMT-2000 requirements and are approved as 3G standards by ITU, these are typically not branded 3G, and are based on completely different technologies.
