Present day:
Since the early 2000s, all telephone numbers beginning with "07" in the UK are either mobile, pager or personal 'find-me-anywhere' numbers. They are all 11 digits long.
Specifically:
Numbers beginning 070 are 'personal' numbers that the owner can redirect as required (e.g. to work, home, mobile phone depending on time of day). These can cost up to 50p/minute to call.
Numbers beginning 076 are for pagers, while numbers beginning 075, 077, 078 or 079 are mobile phones.
Historically:
Before the national renumbering carried out in 1994, 0702 would have been the area code for Southend-on-Sea in Essex. This has since been replaced with 01702.
