Advanced Info Service Plc (AIS), Thailand's biggest mobile operator by subscriber base, has petitioned the Central Administrative Court to revoke the National Broadcasting and Telecommunications Commission's (NBTC) resolution that allows the passage of the planned merger of True Corporation and Total Access Communication (DTAC).
The petition was filed by AIS subsidiary Advanced Wireless Network (AWN) on Nov 11, according to a telecom industry source who requested anonymity.
