The National Broadcasting and Telecommunications Commission (NBTC) plans to review terms and conditions governing consumer protection laws for mobile-phone users.
The move is aimed at preventing duplication of the Consumer Protection Board's role and accommodating the arrival of full commercial third-generation (3G) wireless broadband service next year.
NBTC commissioner Suthipol Thaweechaikarn acknowledged that the watchdog has yet to form a single committee handling consumer protection for mobile subscribers as stipulated under the Radio Frequency Allocation Act of 2010.
The act requires the NBTC to set up a consumer protection committee to deal effectively with customer complaints and investigate and resolve problems before submitting the resolutions to the NBTC board.
But Mr Suthipol said the authority of the NBTC's consumer committee appeared to duplicate that of the Consumer Protection Board.
In practice, the NBTC mainly supports the work of the Consumer Protection Board, resulting in poor operations.
"We are now unable to consider complaints within 30 days as required by the Radio Frequency Allocation Act," said Mr Suthipol.
"It's time to review terms and conditions of the consumer protection law in anticipation of a sharp increase in complaints from 3G mobile users."
