Tonga may not get comms back any time soon: Tonga’s undersea cable could take weeks to repair:
The cable carries … internet and phone communications in and out of Tonga.
It was damaged after the Hunga Tonga-Hunga Ha’apai volcanic eruption … could cost … $US250,000+ to repair

That'll be a big undertaking! As much as I enjoy grousing about the internet it would be scary to get cut off during a time of crisis.
