It is very similar to the 3GP file format but consumes less space & bandwidth, and has some extensions and limitations in comparison to 3GP.ģGP is defined in the ETSI 3GPP technical specification. It is used on 3G mobile phones but can also be played on some 2G and 4G phones.ģG2 (3GPP2 file format) is a multimedia container format defined by the 3GPP2 for 3G CDMA2000 multimedia services. 3GP (3GPP file format) is a multimedia container format defined by the Third Generation Partnership Project (3GPP) for 3G UMTS multimedia services.
