In telecommunications, the terms multi-band, dual-band, tri-band, quad-band and penta-band refer to a device (especially a mobile phone) supporting multiple radio frequency bands used for communication. In the mobile case, the purpose of doing so is to support roaming between different countries/regions whose infrastructure cannot support mobile services in the same frequency range.

Boldly stolen from WikiPedia

Vodafone UK say,
European GSM networks generally use 900MHz and 1800MHz frequencies and most UK phones can use both - these are called dual-band phones.

Some networks in regions such as the USA, Canada, the Caribbean and South America use the 1900MHz frequency. To use these networks you will need a tri-band phone. This phone lets you use not only the 900MHz and 1800MHz frequencies but also the 1900MHz frequency.

Networks that operate on the 850MHz frequency are not very common however, some Southern and Central American, and Caribbean networks do use this frequency. There are a few quad-band phones which use the 850MHz networks as well.
