Numbers beginning "07" in the United Kingdom are used for mobile phones, pagers and 'personal numbers' which are not linked to a specific location.
In particular, numbers beginning "070" are personal numbers which are allocated to individuals or businesses who can then redirect incoming calls to any phone they choose, as and when they please.
For example, somebody might give out an 070 personal number as their contact number and then set it up to forward calls to their work phone in the daytime, their home phone at night and their mobile at other times, rather than giving out separate home/work/mobile contact numbers.
Note though that 070 numbers are easy to obtain for free, so are sometimes used by scammers trying to conceal their real phone number. Be careful, and maybe try searching the web for the full number before you ring it, just to check it out!
