Discussions have finally begun on allowing mobile phone users to keep the same number if they switch carriers, and thus avoid the hassle of having to inform all their contacts about a new number.

The Public Management, Home Affairs, Posts and Telecommunications Ministry recently launched a study group made up of consumers, mobile carriers and academics to study the introduction of the "number portability system" for mobile phones. But carriers are less than enthusiastic, citing the huge setup costs and availability of alternatives.

Currently, wireless phone numbers are unique to each carrier, meaning users need to get a new number if they change carriers.
