The international undersea cable between Tonga and Fiji has been restored, returning data connectivity to the outside world, communications company Digicel says.
Tonga went offline after last month's volcanic eruption caused multiple faults and breaks in the vital communications cable that connects the pacific nation to the international network.
"We have learnt some tough lessons and we know how important internet connection is to our people," Digicel Tonga chief executive Anthony Seuseu said on Tuesday.
Australia's Telstra was among the international partners that helped to provide intermittent internet services, flying in equipment on the first aid flights.
The domestic cable is still down so there's no communication in Vava'u, the company said.
Digicel's technical team has set up a satellite link to restore connectivity for Ha'apai Island and are working on trying to get Vava'u back online this week.
