80 per cent of Vanuatu's mobile network, Digicel, has been restored after the destruction caused by Cyclone Pam.
The network was reconnected on Friday for residents of the northern Islands, including Efate.
However, a Digicel customer care person, Joyce Ovarahu, says service is yet to resume in the badly hit south.
"The only islands in the south including the main island, Tanna, which was badly damaged, those are the islands where we have work going on now, and our team is there working very hard."
Domestic radio services are also being restored.
