Consumer advocates announced on Wednesday that mobile users are, collectively, paying THB3.2 billion monthly for phone time they aren’t using.

They said it is because the carriers are refusing to charge using the amount of seconds used by callers, instead choosing to round up to the next minute and charging customers for lots of airtime that they aren’t using.

Independent Committee for Consumer Protection (ICCP) spokesperson Ruj Komolbut said that the government has said that the carriers must charge by the second but that the carriers haven’t complied, reported Bangkok Post.

The law regarding charging by the second was announced by government officials almost a year ago, on Jan. 6, but it seems that the National Broadcasting and Telecommunication Commission (NBTC) has not made any steps toward complying.

It might not seem like much, but rounding up to the next minute of airtime can really add up on your mobile bill. Advocates say that it’s incredibly unfair, especially when some carriers charge as much as THB1.5 per minute.

The only companies that are currently complying with the new regulation are TOT and TrueMove.

Saree Aongsomwang, also from ICCP, said that because of the illegal fees, the average user is paying THB40 each month more than what they should be paying. When you take into account the 80 million mobile accounts in Thailand, the overcharges total THB3.2 billion each month.
