HelloRoam -- Highest Composite Score
HelloRoam scores 4.64/5 on our rubric overall for Guernsey, with App 5.0 and Support 5.0 on an iOS and Android app, live chat plus WhatsApp, and a 180-day refund. Plans price from $3.50/GB, above the island's own $3.04/GB tracked floor but backed by 204+ carrier partnerships and a 63-language checkout. Guernsey's small-island coverage, confirmed as strong throughout by enrichment data, makes local network routing less of a concern here than in larger, patchier markets.
Dimension scores, 0-5 on our rubric
Pros
- 186 countries with 204+ carrier partnerships for reliable local routing
- Fixed plans from $3.50/GB across popular destinations
- Unlimited plans from $5 for short stays, scaling by duration
- iOS and Android app with in-app top-up, add-destination, and usage alerts
- Live chat, WhatsApp, and email support, including real-time channels
- 31+ local currencies supported at checkout
- 63-language interface for non-English travelers
Cons
- Newer brand (launched August 2025) with shorter track record
- 186 countries, behind Airalo's 200+ catalogue
Airalo -- Widest Coverage Catalogue
Airalo's $4.50/GB starting rate sits above Guernsey's own $3.04/GB tracked floor, one of the few destinations in this comparison where the island's own per-GB rate beats Airalo's baseline. Its Discover Global bundle, covering up to 130 countries on one eSIM, still suits travelers pairing a Guernsey stop with a wider UK or European itinerary despite the higher per-GB entry price.
Dimension scores, 0-5 on our rubric
Pros
- 200+ countries with the widest coverage breadth in the market
- Regional multi-country bundles (Asialink, Eurolink, Discover Global)
- Automatic in-app install with real-time data tracking and hourly runtime estimates
- Airmoney cashback rewards (5-10% depending on loyalty tier)
- Established brand since 2019 with proven reliability
Cons
- Per-GB pricing higher than budget alternatives
- Unlimited plans available in select markets only, not all 200+ destinations
- No live chat or WhatsApp channel: support runs on email and in-app messaging
Saily -- Best for Privacy
Saily prices Guernsey at $3.99/GB with a bundled NordVPN connection at no extra cost, useful since VPN access stays unrestricted per enrichment data. Its 200-country footprint and 4.6/5 on the rubric App score sit above Guernsey's own $3.04/GB comparison floor, making the bundled VPN the stronger differentiator here than raw price.
Dimension scores, 0-5 on our rubric
Pros
- Backed by NordVPN parent company Nord Security with proven privacy infrastructure
- Integrated VPN protection included on every plan at no extra cost
- Clean, privacy-focused app with VPN toggle inside the eSIM interface
- 200 countries with strong European coverage
- 30-day refund policy
Cons
- Email-only support with no live chat or WhatsApp for urgent help
- Fixed data plans only; no unlimited daily tier
- 200 countries, just behind Airalo's 200-plus
Holafly -- Best Unlimited Daily Rate
Holafly's $2.99/day unlimited rate is the only unlimited-style option available for Guernsey, an island with no unlimited tier tracked in this comparison's own country data. Its 4.5/5 on our rubric Pricing score, second only to Nomad's 4.8/5, makes the flat daily rate a real alternative to a fixed-data-only lineup capped at four tiers up to 20GB.
Dimension scores, 0-5 on our rubric
Pros
- Unlimited daily data from $2.99/day with no data caps
- 160+ countries covered including all major destinations
- Simple per-day pricing: know exactly what you pay before you leave
- 180-day refund policy on unused plans
- 24/7 chat support alongside email
Cons
- Speeds reduce after the daily fair use threshold on most plans
- Hotspot tethering limited to 1 GB/day on select destinations
- Not cost-effective for light data users (under 3 GB/trip)
- Fewer countries than Airalo
Nomad -- Best Budget Per-GB Rate
Nomad's $3.00/GB rate is the lowest fixed floor across all five providers, edging just under Guernsey's own $3.04/GB tracked rate by four cents per gigabyte, the tightest margin in this comparison's data. Its 200-country footprint and email-only support window are real trade-offs on an island enrichment data already describes as carrying good coverage.
Dimension scores, 0-5 on our rubric
Pros
- Competitive pricing starting from $3.00/GB in Southeast Asia
- Simple, fast checkout with no account required in many cases
- Lowest per-GB rates for Thailand, Vietnam, South Korea, and Japan
- Plans start at a low entry price for short trips
Cons
- Email-only support with no live chat, WhatsApp, or phone channel
- Basic app compared to Airalo and Saily
- 200 countries, behind only Airalo among the five providers
- Limited plan variety in some countries

FAQ
Guernsey eSIM questions, answered
Which eSIM has the cheapest per-GB rate for Guernsey?
Which eSIM has the cheapest per-GB rate for Guernsey?
This comparison's Guernsey data floors at $3.04/GB on the 20GB plan. Among the five providers, only Nomad's $3.00/GB edges below that floor, by four cents per gigabyte. HelloRoam ($3.50/GB), Saily ($3.99/GB), and Airalo ($4.50/GB) all price above Guernsey's own tracked rate, and Holafly's $2.99/day removes per-GB math entirely.
Does Guernsey have an unlimited eSIM plan?
Does Guernsey have an unlimited eSIM plan?
No. This comparison tracks no unlimited tier for Guernsey, one of the few destinations in this expansion without one. The island's lineup stops at four fixed-data plans up to 20GB, skipping a 10GB middle tier entirely. Holafly's $2.99/day unlimited rate is the closest unlimited-style alternative, priced separately from this island's own tracked data.
Does Guernsey have 5G eSIM coverage?
Does Guernsey have 5G eSIM coverage?
This comparison tracks only 4G for Guernsey, carried by Sure, the sole network type recorded across all five providers compared here. Enrichment data lists JT and Airtel-Vodafone as additional local carriers, and separately describes Guernsey as a small island with good coverage throughout, regardless of the network generation tracked.
Why does Guernsey skip a 10GB eSIM plan size?
Why does Guernsey skip a 10GB eSIM plan size?
This comparison tracks only four fixed-data tiers for Guernsey: 1GB, 3GB, 5GB, and 20GB, the shortest lineup in this expansion and the only one to skip a 10GB middle option. The jump from 5GB straight to 20GB is the widest single gap between consecutive tiers tracked for any destination here.
Does buying a bigger data plan lower the per-GB cost in Guernsey?
Does buying a bigger data plan lower the per-GB cost in Guernsey?
Yes, in this comparison's data. The 1GB plan costs $5.04 per GB, while the 20GB plan drops to $3.04 per GB, a 40% reduction across the four tracked plan sizes. Larger fixed-data plans price lower per gigabyte than smaller ones throughout Guernsey's lineup.
Does a VPN work with a Guernsey eSIM?
Does a VPN work with a Guernsey eSIM?
Yes. Enrichment data lists Guernsey's VPN status as unrestricted, so a VPN app works alongside any of the five eSIM providers compared here. Saily bundles a NordVPN connection into every plan at no extra cost, an option worth weighing against a separately downloaded VPN app.
Which eSIM offers the best support for a Guernsey trip?
Which eSIM offers the best support for a Guernsey trip?
