Mobile Networks in Guernsey

Guernsey has two main mobile operators: Sure Guernsey and JT Guernsey (part of the Jersey Telecom group). Both provide 4G LTE coverage across the island and its smaller dependencies including Herm, Sark, and Alderney.

St. Peter Port, the capital and main harbour, has excellent 4G coverage. The airport at St. Andrew and main road corridors have solid signal. Guernsey is a small island (about 65 square kilometers) so coverage is comprehensive across most populated areas.

Sark, one of the smaller Channel Islands, is car-free and has basic mobile coverage. Herm is tiny and has limited coverage. Alderney, the third main island in the Bailiwick of Guernsey, has coverage in St. Anne town. WWII bunkers, tunnels, and fortifications are tourist attractions across the island, but underground areas have no mobile signal. Australian travellers should confirm their handset is unlocked and supports the local network bands.

Sure: 4G

Best Time to Visit Guernsey

May to September is the main season. The island is quiet outside summer.

Network demand is higher in peak tourist periods. A HelloRoam eSIM means you are not competing for crowded public Wi-Fi at popular spots.
