Our list of best 3G cellphones has some of the best smartphones and advanced feature phones. The 3G (third generation) network technology provides faster data communication than the 2G's (second generation) EDGE technology used in GSM cellphones. 3G technology is not only about speed and high data transfer rate, but also about its efficiency during data transfer by efficient usage of available data communication resources.
When compared to 2G EDGE technology which supports few hundreds of kbps, the cellphones compatible with 3G network allow data rates of 3Mbps and even far more depending on the carrier you choose.
The best 3G cellphones support some of the useful features like video calling, faster web access along with faster online streaming of music and high resolution videos, and playing online multiplayer games.
Most smartphones running on Android, iOS, Blackberry and Windows support 3G networks for faster access to various productive web apps. Web surfing on the smartphones is also supported by faster downloading of various files including music, videos and games
Various technologies in the third generation which the carriers in the US deploy, are listed below.
CDMA technology, using CDMA2000 and EVDO standards, started offering 3G wireless network support, delivering high-quality voice and high-speed data. Such CDMA cellphones are available from Verizon and Sprint carriers.
When compared to the other 3G standards, the mentioned standards here have some drawbacks like lower data speeds and inability to simultaneous voice and data transmission.
UMTS is a 3G network standard using CDMA technology which is actually an enhancement to the GSM in 2G.
UMTS uses CDMA technology for faster data transmission and secured data encryption. And it is called as an enhancement to the GSM because, the 3G cellphones using this standard support features like international roaming and can deployed by GSM carriers like AT&T and T-Mobile.
UMTS is also known as 3G GSM or W-CDMA.
HSPA is another 3G standard and an extension to UMTS, introduced for improved performance when compared to the existing 3G networks in terms of data rates. The data speed with HSPA is over 2Mbps from carriers like AT&T and T-Mobile.
