Frequently Asked Questions
No! This is the most common mistake. Although Guernsey is a British Crown Dependency, it is NOT part of the UK and NOT in the European Union. Therefore, "Roam Like at Home" (EU) and standard UK carrier plans DO NOT APPLY. Most UK and EU providers will charge you expensive international roaming rates (e.D., £2-£6 per day or £2 per MB). A Cellesim Guernsey eSIM is far cheaper and saves you from a massive shock bill.

This specific plan is valid only for Guernsey. The "Bailiwick of Guernsey" and the "Bailiwick of Jersey" are two separate jurisdictions with different telecom networks. If you plan to "island hop" and visit Jersey as well, you will need a separate plan or check our Channel Islands Regional eSIM (if available) to stay connected in both places.
To give you the best coverage on the island, our eSIM connects to Guernsey's top-tier providers, typically Sure or JT (Jersey Telecom). These networks provide excellent 4G/LTE coverage across the main island, ensuring you stay connected whether you are in St. Peter Port or exploring the coastal cliffs.

Yes. The local networks (Sure/JT) have towers that provide coverage to the other islands within the Bailiwick, including Herm, Sark, and Alderney. While the signal might be 3G in the most remote parts of Sark (which has limited electricity), you will be connected in the main village areas, which is far better than relying on public Wi-Fi.
Yes, for convenience and price. Buying a physical SIM at the airport (if the kiosk is open) requires you to register your ID and swap your tiny SIM card. Our eSIM is 100% digital. You can buy it online, install it before you fly, and be connected the moment you land, all while keeping your home number active for calls.
No, Uber does not operate in Guernsey. You need reliable data to use the buses.gg app for live bus times or to find local taxi numbers on Google Maps.

Yes. You will have strong signal at The Little Chapel in Saint Andrew, allowing you to upload close-up photos of the intricate colorful mosaics instantly.
Yes. Coverage is excellent along the west coast at Cobo Bay, making it easy to live-stream the famous sunsets or video call friends from the beach.
Absolutely. Many of Guernsey's scenic lanes (Ruettes Tranquilles) have a 15mph speed limit and few signs; reliable data for Google Maps is vital to explore them without getting lost.
Look up your phone’s exact model number with the manufacturer to see if it’s listed as compatible, and make sure your phone is not carrier-locked. Seeing an EID number or an “Add eSIM” option in your settings is a good sign, but some phones have regional restrictions. If you’re not sure, please contact our support team before you buy.

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:
- 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).
- This means your "Roam Like at Home" (RLAH) plan from the EU DOES NOT APPLY.
- 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) 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 $5.60 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.
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.
