WHAT IS 3G2?
The 3G2 format was created by the 3rd Generation Partnership Project 2, or 3GPP2. This format is mostly used on 3G (and some 2G and 4G) phones for transmitting multimedia over cellular networks. We’ve provided specifications for the 3G2 file type below.
A 3G2 file can contain video (encoded with the MPEG-4 or H.264 codec), audio (encoded with the EVRC, QCELP, SMV, or VMR-WB codec), and timed text. 3G2 is very similar to its predecessor, 3GP, but is designed to consume less bandwidth and storage space. Most likely, you can play a 3G2 file on your phone, but you might find it difficult to open these videos elsewhere. Below are listed some of the programs that support the playback of 3G2 files. Refer to this list if you’re not sure how to open these videos.
