eSIM Guernsey: Don't Fall for the "Not in the UK/EU" Roaming Trap!

Welcome to Guernsey, the beautiful Channel Island known for its stunning coastline, rich history, and the charming capital of St. Peter Port. Whether you're flying in for business, exploring the neighbouring islands of Sark and Herm, or visiting historic sites, a reliable connection is essential.

Stay connected in this unique Crown Dependency with Cellesim's Guernsey eSIM plans, starting at just $4.76. Choose from 20 limited and 16 unlimited plans.

CRITICAL WARNING: Guernsey is NOT in the UK or EU!

This is one of the most common and expensive "roaming traps" for all travelers, including those from the UK and Europe:

1. Guernsey is a self-governing Crown Dependency. It is NOT part of the United Kingdom (UK) and it is NOT part of the European Union (EU).
2. This means your "Roam Like at Home" (RLAH) plan from the EU DOES NOT APPLY.
3. Crucially, most UK mobile plans (Vodafone, O2, EE, Three) DO NOT include Guernsey in their standard "domestic" UK plans.

The Trap: The moment you land at Guernsey Airport (GCI) or arrive by ferry, your phone connects to a local network (e.g., Sure, JT) and your home carrier will charge you astronomical "Rest of World" roaming fees.

A Guernsey eSIM is the only smart way to get affordable, high-speed data and avoid a massive surprise bill.

Why a Cellesim eSIM is Essential for Guernsey

• Avoid the Roaming Trap: Our eSIM is your shield against "bill shock". Don't pay £2 per MB for data.
• Instant (GCI) Airport Connection: Get online the moment you land at (GCI) Airport. This is critical for activating your GPS, checking car rental details, or contacting your guesthouse.
• Keep Your Home Number: Your eSIM handles the data, so your primary SIM (and your WhatsApp number) remains active for important calls and texts.
• Excellent 4G Coverage: We partner with top local operators to provide the best available 4G/LTE connection across St. Peter Port and the main island.

Stay Connected in Guernsey's Key Hubs

1. St. Peter Port & (GCI) Airport

Your journey begins at Guernsey Airport (GCI) and the beautiful capital. An eSIM for St. Peter Port is essential for finding restaurants, navigating the cobbled streets, and checking ferry times to Sark and Herm.

2. St. Sampson

The island's second-largest town and a key commercial port. A reliable connection here is key for business and logistics.

3. Sark & Herm

While coverage on the smaller, car-free islands of Sark and Herm can be limited, your eSIM will provide the best possible service when visiting for the day.
