What does triband mean in mobile phones?
Tri band phones (also known as tri-band or triband) are mobile phones that support three frequency bands. Having more than one frequency in one device is useful to enable roaming between different countries that peg the allowed transmission frequency at different values or to allow a better coverage in the same country. Various countries use different frequency bands for their mobile networks, and a triband phone can be used on three of these bands, generally speaking, chosen to favour two of the home country’s bands, and one for roaming in other countries. In summary GSM frequency bands used around the world are: * 850 MHz (In America) * 900 MHz (In Europe and many parts of Asia) * 1800 MHz (In Europe and Asia) * 1900 MHz (In America) 2G Triband phones are mobile phones that support the GSM 900/1800/1900 MHz bands (commonly sold in Europe, Asia, and Africa), or alternatively the 850/1800/1900 bands (commonly sold in the Americas).
