Dual Band
A phone that is capable of operating on two out of the four major GSM bands - in the UK, they operate on 900 MHz and 1800 MHz. The GSM 850/1900 MHz phone will work in the Americas, whilst any GSM 900/1900 phone will work on at least one of the network in most countries around the world. All new UK phones are now dual band.
