Let PlanPilot™ AI Find Your Best 5G eSIM for Guernsey

Official Languages: English, French

English Is the Language of Daily Life, Government and Business across Guernsey. Guernésiais, the Island's Own Norman Dialect, Now Has Very Few Fluent Speakers, and French, Once the Language of Law and Church Records, Survives Mainly in Parish and Place Names. Both Were Given Formal Recognition Alongside English in 2020

Mobile Network: 4G Covers the Main Island Reliably, Including Most Roads and Villages, and a 5G Upgrade Began around Saint Peter Port in 2026 before Extending Outward. Coverage Is Patchier on Sark, Herm and Alderney and Can Drop to an Older Generation Away from Village Centres, so Do Not Count on a Signal on Remote Cliff Paths

Roaming/SIM/eSIM: A UK Mobile Plan Does Not Treat Guernsey as Home Territory, and EU Roam-Like-Home Rules Do Not Apply Either, since Guernsey Sits outside Both. Expect International Roaming Charges Unless Your Plan Names the Channel Islands. A Local SIM Suits a Longer Stay If Your Phone Is Unlocked, While an eSIM Set Up before You Travel Activates the Moment You Land and Skips a Shop Visit. Check Whether Sark, Herm and Alderney Share the Same Allowance as Guernsey

Cards and Contactless Payment Are Accepted Almost Everywhere in Saint Peter Port and the Larger Towns, Including Hotels, Restaurants and Supermarkets. Carry Some Cash for Rural Honesty Boxes, Market Stalls and the Smaller Islands, Where Card Machines Are Less Common. Guernsey Pound Notes Are Not Legal Tender in the United Kingdom, so Spend or Exchange Them before You Leave

Tipping Is Modest and Never Obligatory. Check the Bill First, since Restaurants Often Add a Service Charge of around Ten to Twelve and a Half Percent Automatically; If Not, Rounding Up or Leaving a Similar Amount Is Appreciated. Cafes and Taxis Are Usually Rounded Up Rather than Formally Tipped, and a Small Tip for a Porter or Particularly Helpful Hotel Service Is a Courtesy, Not an Expectation

Plug Type: Type G

Voltage: 230V, 50Hz

Adapter: Visitors Already Using Type G Plugs, Including from the United Kingdom and Ireland, Do Not Need an Adapter. Visitors from Continental Europe, North America and Most of the Rest of the World Will Need a Type G Adapter, since Guernsey Follows the British Standard Rather than the Two-Pin European One
