The ATTWS T637 can certainly be unlocked, but even if you do unlock the phone it's not a 'world phone'. If the network you are trying to access in the UK is at 900 MHz, this phone wont work.

The T637 is simply a North American version of the international T630. Aside from network frequency (The T630 contains GSM 900 / 1800 / 1900 MHz whereas the T637 uses GSM 850 / 1800 / 1900 MHz) and colors, the two phones are identical.
