A Personal Numbering Service is typically identified as a number that starts 070.
It can be used by companies and individuals that travel overseas and allows them to redirect calls to any number. This means they can keep their number wherever they are in the world.
Calls to these numbers can vary from 4p to £3.40 per minute from a landline and can include a set up fee of up to 51p. Calls from mobiles can vary from 30p to £1.50 per minute.
