Mobile phone users have been warned to watch out for extra charges if they switch to another network. From next month, phone owners will be able to join a new network and keep their old number. The council said phone companies were obliged to allow users to take their number with them, and had no right to charge them a fee for it. Phone owners were also warned to check the terms of the agreement with their current company, as fees might be imposed if the contract was for a set period and they wanted to opt out early.
