Plans matched to your trip length
The cheapest provider changes based on how long you stay. Work through these steps to land on the right plan without over-paying.
- 1 · Pick your trip lengthUse the 7 / 14 / 30 day tabs in the comparison table below. Each tab re-ranks providers by estimated cost for that duration, so the top row is the most affordable match for your travel window.
- 2 · Choose fixed or unlimitedShort stays (under 7 days) almost always favor a fixed-data plan. At 14+ days, unlimited daily rates can undercut fixed plans if you stream video. The table shows both side by side at your selected duration.
- 3 · Install before you flyPurchase on the provider's official site, scan the QR code at home on Wi-Fi, and add the eSIM as a second line. Your home SIM stays active throughout.
- 4 · Activate on arrival in GuernseySwitch your data line to the travel eSIM when you land. Most plans start counting data only from first connection, not from purchase, so you don't lose a day in transit.

A weekend in Guernsey (3 days) needs about 5GB. A 5GB plan costs $20.70, which works out to $6.90/day. Extend to a 7-day trip and the 20GB plan at $60.83 ($8.69/day) becomes the better fit. Compare plans by your exact travel dates to avoid paying for unused data.
A 14-day stay calls for the 20GB plan at $60.83, or $4.34/day.
Fixed 20GB at $60.83 covers 13 days of moderate use.

Guernsey eSIM FAQ
Frequently asked questions
Which eSIM plan fits a weekend trip to Guernsey?+
A 3-day trip to Guernsey on Sure's 4G LTE network needs 1.5GB for a light user (maps and messages only), so the 3GB at $12.69 is enough. A moderate user using social media and navigation needs 4 to 5GB, so go with the 5GB at $20.70. Heavy users streaming or video-calling need 10GB or more; buy the largest fixed plan available. For a typical weekend traveler, the 5GB at $20.70 fits most weekend travelers without overpaying for unused data.
How does eSIM cost change for 7 vs 14 vs 30 days in Guernsey?+
Per-day data cost in Guernsey drops as trip length increases. 7 days: 20GB plan at $60.83 total ($8.69/day). 14 days: 20GB plan at $60.83 total ($4.34/day). 30 days: 20GB fixed plan at $2.03/day. The 14-day bracket balances daily rate and flexibility for most travelers visiting Guernsey.
Can I top up or extend my eSIM mid-trip in Guernsey?+
Running low on data in Guernsey? All four providers offer in-app top-ups that activate in seconds. Airalo lets you buy additional data through the app in real time, and the top-up activates within 60 seconds. Saily and Nomad both support fixed-data top-ups with no reinstallation. A top-up of 1GB costs $5.04, the same as buying a new plan. Buying a larger plan upfront is cheaper per GB than topping up, but the option is always available if you underestimate your usage.
Does eSIM work in Guernsey?+
Yes, eSIM coverage in Guernsey runs on Sure at 4G LTE. Samsung Galaxy S22 and later, iPhone XS and later, and Google Pixel 4a and later are all compatible. Make sure your device is unlocked from its original carrier, then scan the QR code before you leave home.
Does unused Guernsey eSIM data roll over to the next trip?+
No. Travel eSIM data in Guernsey expires at the end of the plan validity window, and unused gigabytes do not carry over to future trips or additional purchases. Buy a plan that matches your actual trip length, not a larger buffer. A 7-day Guernsey plan like the 20GB tier at $60.83 expires after 7 days whether you use all 20GB or not. If your trip ends early, most providers (Airalo and Holafly) offer refund policies on unused plans within their support window.
Can I use a Guernsey eSIM across multiple European countries on one trip?+
A Guernsey-specific eSIM only covers Guernsey. For multi-country European trips, Airalo's Eurolink bundle covers 39 EU countries on a single plan with no swapping required at each border. If Guernsey is your only stop, a single-country plan is cheaper: 20GB at $60.83 for a 7-day trip. EU roaming rules do not apply to travel eSIMs because each plan is a standalone purchase.
Does my Guernsey eSIM stay active when I cross into a neighboring country?+
No, a single-country Guernsey eSIM deactivates outside Guernsey's borders. Plan your data use for the exact days you are in Guernsey. For trips combining Guernsey with other European stops, a regional bundle covers the full itinerary on one purchase. A 20GB plan at $60.83 fits a two-week Guernsey stay, but it stops working the moment you cross the border.
Is a 7-day or 14-day Guernsey eSIM plan better value?+
Longer plans in Guernsey cost less per day than shorter ones. A 7-day stay fits the 20GB plan at $60.83 ($8.69/day). A 14-day stay fits the 20GB plan at $60.83 ($4.34/day). Buying one correctly-sized plan costs less than buying two smaller plans back-to-back.
What 4G LTE coverage can I expect on a full Guernsey itinerary?+
Guernsey eSIMs run on Sure at 4G LTE. Coverage holds reliably in tourist areas and city centers. For a full-country itinerary, check the detailed network map before finalizing your carrier preference.
How do I choose an eSIM plan for Guernsey?+
Estimate 1.5GB per day for typical travel use. Plans for Guernsey start at $5.04 for 1GB. Pick the plan that covers your full trip length so you do not run out mid-stay. If your trip is shorter than the plan window, the remaining days simply expire.
