Users of mobile phones in Jersey can now move their phone number from one of the three island operators to another. Mobile number portability (MNP) came into operation on 1 December. Jersey cell phone users finally have a real option between using Jersey Telecoms, (which was first into the market) followed by Sure (Cable and Wireless) and then Airtel-Vodaphone which was last into the field in 2007. Until now users have had to have a new number when signing a contract with another cell phone operator. The first case to requesting MNP was put to the Jersey Competition Regulatory Authority in 2006.

The change from one operator to another may take two days to complete and anyone transferring a number must then stay with the new company for at least two months.
