The three Thai cellcos which submitted the only bids for next week’s scheduled 2100MHz 3G licence auction – AIS, DTAC and True Move – are all qualified to enter the contest, the National Telecommunications Commission (NTC) has announced. Two licences are up for grabs in an initial round with a starting price of THB12.8 billion (USD423 million), whilst a third licence will be put up for auction within 90 days. However, Reuters reports that state-owned CAT Telecom is planning to submit an appeal to the Central Administrative Court on Monday in an attempt to block the process. It says its interests will be damaged by the auction and that the NTC has no authority to offer the 3G licences. A similar blocking lawsuit from a representative of CAT’s sister telco TOT was recently thrown out of court.
