Tonga lost its internet and phone connections on Sunday last week when the Tonga Cable linking it with Fiji was cut.
A second cable to the outer islands was also severed.
A government spokesperson, Lopeti Senituli, said there were already talks between Tonga Cable, the Tonga Communications Corporation and the Ministry of Communications, to ensure such a problem doesn't recur.
He said the government had previously been given an understanding there was almost no chance of the cable failing.
