Discussion about mobile phones : 

Discussion about mobile phones In telecommunications, the terms multi-band , dual-band , tri-band , quad-band and penta-band refer to a device (especially a mobile phone) supporting multiple frequencies used for communication 2G Network GSM 850 / 900 / 1800 / 1900 3G Network HSDPA 850 / 900 / 1700 / 1900 / 2100 – Based on above shown frequency bands, a mobile is decided whether it is 3G compatible or not.

Discussion of mobile phones: 

Discussion of mobile phones In simple terms ,3G means the amount of data that network distribute it to a device. Currently most of the latest handsets from different brands like Nokia, Sony Ericsson, LG, HTC, Blackberry and numerous others come equipped with 3G facility. its powerful tools like HSDPA, EDGE and GPRS act as boosters and which in turn enhance the performance of this device.
