Does my EU roaming plan also apply on Guernsey?

No. Guernsey is part of neither the EU nor the EEA. EU roaming rules do not apply here, so your German provider can charge normal international roaming fees. With a Reisechip eSIM you avoid those costs entirely.

Does the eSIM also work on the neighbouring islands of Herm and Sark?

On Herm and Sark, network coverage is much more limited, as there is no mobile infrastructure of their own. On Guernsey itself and near the coast towards Herm the network can be stable, but on Sark you should expect very limited or no reception.

Do I need a plug adapter on Guernsey?

Yes. Guernsey uses British type G sockets. Devices you bring from Germany will not fit directly, so pack a travel adapter, so that you can use your smartphone for charging and for setting up the eSIM without trouble.

How much data do I need for a holiday on Guernsey?

For a one-week stay with navigation, ferry times, social media and the occasional bit of streaming, we recommend 3–5 GB. Because the island is compact and most hotels offer Wi-Fi, even 2–3 GB is often enough for more relaxed travellers.

Is Guernsey part of the UK? Does the British mobile network apply here?

Guernsey is a British Crown Dependency, but not part of the United Kingdom. The mobile network is run by its own local providers (Sure, JT and Airtel-Vodafone) and is not the same as the British networks on the mainland.

How much does an eSIM for Guernsey cost?

eSIM data plans for Guernsey start at €1.99. You pay once for the data you choose — no contract, no monthly fee and no surprise roaming bill. Bigger data packs and longer validity cost more.

Will I keep my German phone number with an eSIM in Guernsey?

Yes. Your German SIM and number stay active, and the travel eSIM runs alongside it as a data-only plan. You stay reachable on WhatsApp, iMessage or over Wi-Fi while browsing on the local network. Normal calls and texts still go through your German number, where roaming charges may apply.

Can I top up or extend my Guernsey data plan?

Yes. When your data runs out or the plan expires, just buy another pack. The eSIM profile already on your phone stays in place, so there is nothing to reinstall and you stay online without a break.

Can I use the eSIM as a Wi-Fi hotspot in Guernsey?

Yes. You can share the connection with a laptop, tablet or a travel companion through your phone's personal hotspot. Hotspot use comes out of the same data allowance, so choose a slightly larger pack if you plan to tether.

Should I install the eSIM before I leave or after I arrive?

Install it at home over Wi-Fi before you travel. The data plan switches on automatically when your phone joins a network in Guernsey, so you are online the moment you land instead of hunting for airport Wi-Fi.

Will the eSIM work on my phone?

It works on any eSIM-capable phone, including iPhone XS and later, Samsung Galaxy S20 and later and Google Pixel 3 and later. The phone must also be unlocked (not tied to one network). To check yours, look for "Add eSIM" under Mobile Data or Connections in your settings.

Guernsey is only about two hours' flying time from Germany, yet the Channel Island feels like another world: rugged cliffs, medieval castles, blooming gardens and a relaxed Anglo-French way of life. If you explore the hidden bays, stroll through St. Peter Port or visit the neighbouring islands of Herm and Sark, you need a dependable mobile network for navigation, ferry connections and restaurant tips. Because Guernsey is not an EU member, there is no EU roaming protection. With a Reisechip eSIM you can travel the island at ease, without nasty surprises on your bill.

Why get an eSIM for Guernsey?

Guernsey is a Crown Dependency of the British Crown and not part of the EU, which means EU roaming does not apply here, and your German mobile contract can cause unexpected roaming costs on the island. A Reisechip eSIM protects you from that and connects you directly to the local network of Sure, JT or Airtel-Vodafone, which covers 98% of the island with 4G/LTE. A practical point: Guernsey is only 78 square kilometres, so you are constantly on the move, between stretches of coast, small villages and boat trips to the neighbouring islands. Everywhere you need maps and current ferry times. You install the eSIM at home before you fly and are connected as soon as you land at Guernsey airport. No SIM swap, no adapter problem, so you can simply get going.
