The US telco said it plans to enhance its service portfolio with managed LAN, IP and application services.
Previously, AT&T sold its services in partnership with local providers but now can deliver services directly to multinational customers in Indonesia.
"Many of our key multinational customers have told us they need to be in Indonesia, and while AT&T has been operating a successful business here, the new licence will allow us to deliver an array of new services and make it much easier for us to do business with multinational customers," said Choo Hock Lye, GM of AT&T ASEAN.
The licence was made possible by the Indonesian government’s policy of allowing foreign operators to own up to 95% of communications services. AT&T now owns 95% of the joint venture with PT Pradipta Danadvaska.
AT&T claims to have invested over $4 billion since 2006 in business-focussed international network, systems and applications.
