Herm phones and net 'down for days' following snow
Fixed phone connections in Herm may not be restored until Friday.
The island was left with only mobile telephone and 3G internet after heavy snow and strong winds hit the Channel Islands earlier in the week.
Jonathan Watson, director of hospitality for Herm, said the trouble had started on Monday.
A spokesman for Sure, which provides phone lines and fixed broadband to Herm, said the island's landlines were being treated as a priority.
It said fixed line broadband had been restored on Thursday, and mobile telephones were still working, despite a mast in Herm being out of order.
Mr Watson said: "We're relatively used to losing boats every now and again in winter, but we're not used to losing so much communication.
"Our week of turmoil began on Monday when we had those blizzards and storms, and we lost all internet and landline and email communication."
He added that the boat service between Herm and Guernsey had been suspended, and the island had seen 30 trees felled by the weather.
Mr Watson said islanders had coped with the weather well.
He said: "Supplies and food... we're amazingly resilient on the island, the vast majority of us have large freezers and are stocked up just in case there are one or two days that we can't actually access anything by boat."
He said the island had not been left short of power, as it has its own small power station.
