Mr Somchai said AIS has also reinstated two positions, chief corporate officer and chief strategy officer to support the top management team, which includes chief financial officer, chief human resources officer, chief technology officer and chief marketing officer. AIS announced yesterday that its ser- vice revenue totalled 30.6 billion baht in the third quarter of this year, up 2.2% year on-year. Mr Somchai said third-quarter growth was driven by a higher number of subscribers and ever-rising internet usage.
