Thailand's three largest mobile operators - AIS, Dtac and True Move - have united to oppose current regulations capping tariffs for 3G and 4G services.
The operators brought up their opposition a group discussion with regulator NBTC on Monday, the Bangkok Postreported.
Revising the regulations would encourage greater competition and stimulate the further development of mobile networks and services, the operators claimed.
They have argued that existing caps have diminished the development of service packages, distorted price mechanisms and impeded the operation of an open and competitive market.
Currently the NBTC caps the maximum 3G tariff at 0.82 baht ($0.02) per minute for voice service, 1.33 baht per SMS, 3.32 baht for MMS and 0.28 baht for data services. The equivalent 4G limits are 0.69 baht, 1.15 baht, 3.11 baht and 0.26 baht respectively.
A representative for Dtac stated that other mobile markets with the same level of development as Thailand do not impose tariff caps, and noted that tariffs in Thailand are among the lowest in the ASEAN region.
