All frequencies are 2-2.1 GHz range
The operating frequency for 3G mobile phones typically falls within the range of 1.8 GHz to 2.5 GHz, depending on the specific technology and region. Common bands include 850 MHz, 900 MHz, 1700 MHz, and 2100 MHz. Different countries and carriers may use various frequency bands, so compatibility can vary based on the region.
Yes, a 3G system can use CDMA 800, as CDMA (Code Division Multiple Access) is one of the technologies employed in 3G networks. Specifically, CDMA2000 is a 3G technology that operates in the 800 MHz frequency band, allowing for voice and data transmission. This enables users to access 3G services, such as faster internet speeds and improved call quality, through CDMA 800 networks. However, the availability and performance may vary based on the network provider and coverage in a given area.
Send ACT 3G to 144 (for prepaid) 111(for postpaid) to activate 3G in you mobile..!!! Have Fun..!!!
The band of 3G has a minimum requirement of 200kbit/second. Most companies that offer 3G are providing higher bandwidths than minimally required putting them in the 3.5G and 3.75G range.
The uptake for 3G was fairly slow to begin with as there may not have been the support for the 3G system. Some of the first phones to include 3G include the Nokia 6630, the LG u880 3G, and Ericsson also released their own 3G phone.
New Zealand uses GSM 2G 900/1800 3G 850, 3G 900/2100 AFAIK NZ is in the process of phasing out their aging CDMA networks as is many other carriers around the world.
"the infrastructure MetroPCS is using keeps speeds in the range of older 3G networks
No. 3G stands for third generation phone while GSM stands for Global System for Mobile.
