Advanced Info Service (AIS), Thailand's biggest mobile operator by subscriber base, has written to the National Broadcasting and Telecommunications Commission (NBTC) to express opposition to the planned merger of its rivals True Corporation and Total Access Communication (DTAC), according to a source at the regulator.
The source who requested anonymity said AIS submitted the letter on March 25, urging the NBTC board to carefully handle the deal, which it said would affect consumer interest and competition.
