eSIM Guernsey by Teclapi - Clifftop Coasts & Medieval Charm, Connected

Guernsey moves at a pace that feels refreshingly removed from the mainland. The flower-lined lanes of St Peter Port, the German Occupation museums, the clifftop coastal walks, the sandy beaches of Cobo and Vazon, and a financial and culinary scene that punches well above its weight for an island of 63,000 people. 

Your eSIM Guernsey by Teclapi keeps you connected across this Crown Dependency on two of the island's networks — for up to 30 days.

Enjoy your trip with:

⚡ High-speed 4G LTE data on Manx Telecom and Sure — Guernsey's two established mobile networks combined.

Frequently Asked Questions

Everything you need to know about this eSIM plan.

Install your Guernsey eSIM the evening before your trip begins. Validity starts from the moment of installation — not from purchase and not from first data use. Installing at home the night before means your plan is live and ready the moment you land at Guernsey Airport, with no setup hassle at arrivals.
Always purchase at least one extra day beyond your planned stay. Guernsey's ferry and flight connections to the mainland can occasionally be delayed by weather — the extra day ensures you're covered against any unexpected extension to your stay. Guernsey's relaxed pace also has a habit of making travelers want to linger longer than planned.
Validity starts from the moment you install the eSIM — not when you purchase it. You can buy well in advance without losing any days. Just hold off on installation until the evening before your departure.
Daily plans give you a set high-speed data allowance per day — from 500MB upwards — that refreshes automatically every day throughout your plan's validity. The Unlimited* plan gives you 1GB of full-speed 4G data per day, then unlimited data at up to 5 Mbps for the rest of that day. At 5 Mbps you can use Google Maps, WhatsApp, stream music, and browse social media comfortably throughout your Guernsey stay.
Your Guernsey eSIM automatically connects across JT and Sure — the island's two mobile operators — using whichever delivers the strongest signal at your location. Sure is the largest operator on Guernsey offering the fastest speeds, while JT provides equally comprehensive island-wide coverage. Both JT and Sure have applied for 5G spectrum and the rollout is expected to begin in 2026 — increasing island-wide coverage by a quarter. Having both networks gives your eSIM the strongest possible coverage net across Guernsey's compact landscape.
No manual selection is needed — your eSIM automatically connects to whichever of the two networks delivers the strongest signal at your location, switching seamlessly in the background without any action required on your part.
5G is expected to begin rolling out in Guernsey from 2026, following regulatory approval of applications from both JT and Sure for 5G spectrum access. Until then, 4G LTE is the standard across the island and delivers reliable, fast speeds for all everyday travel use cases — navigation, social media, WhatsApp, and streaming.
Yes. Guernsey is a compact island of just 78 km² — both JT and Sure provide comprehensive coverage across all parishes including Vale, Castel, St Saviour, and the more rural western and southern areas. The only occasional signal gaps occur in very deep rural lanes or along some isolated coastal paths, which is standard for any island network.
No — this plan covers Guernsey and its associated islands only. The Channel Islands are not included in most standard European roaming plans — which is precisely why a dedicated Guernsey eSIM is the most reliable and cost-effective option. For Jersey, check our Teclapi Jersey eSIM. For mainland UK, check our Teclapi UK eSIM. 
No — this is a data-only eSIM for Guernsey. It does not include a local Guernsey number for voice calls or SMS. For all communication needs, WhatsApp, FaceTime, Messenger, and other VoIP apps work perfectly over your data connection.
