Which mobile networks you get in Guernsey

Sure Mobile dominates Guernsey’s published eSIM network lists, with Vodafone the only other named operator. In practice, that means the radio network is largely decided before you choose a plan: most listed options point to Sure Mobile, while Vodafone is the name to look for when a different network matters. The distinctions between eSIMs are therefore likely to lie elsewhere, such as plan terms, data allowances and device compatibility.

Where your data comes out in Guernsey

Breakout varies sharply: one provider routes through nearby Jersey, while others use gateways in the United Kingdom, Austria or the United States. That makes your provider choice decisive. The typical round trip to services in Guernsey is about 58ms, with longer routes adding delay rather than reducing download speed; a foreign gateway also makes you appear to be in its country. For example, a local banking app may refuse a UK, Austrian or US IP even though maps and messaging continue to work normally.

Guernsey eSIM prices, month by month

Data has been getting cheaper in Guernsey: a gigabyte typically goes for $1.09 now, against $2.12 when we started tracking it in December 2025, a fall of 49% across 10 months.

That is 33% below the $1.62 a gigabyte typically costs across the 229 destinations we track — only 86 of them come in lower, which puts Guernsey among the cheapest places in the world to buy mobile data as a visitor. It has never been cheaper: $1.09 in September 2026 is the lowest figure we have recorded for Guernsey.

Every figure here is the lower quartile of the plans in our catalogue that month — the cheaper end of what was actually on sale, rather than an average pulled up by a handful of premium plans.

Frequently Asked Questions about eSIMs for Guernsey

How many travel eSIM brands (providers) are available for use in Guernsey, and how many prepaid data plans are there?

Sure Mobile and Vodafone are the local operators named across the Guernsey listings, while most major travel eSIM brands offer plans for the island. AirHub, RedEx eSIM, MicroESIM, eSimCard, AbestESIM and iroamly have particularly substantial catalogues here, but that is not a quality ranking. The practical choice is therefore less about finding a brand that works and more about comparing the prepaid allowance, validity and what happens after the data runs out. A familiar name may offer several sizes, while another may suit a shorter visit or lighter use.

What are the mobile networks available for a travel eSIM in Guernsey?

Sure Mobile and Vodafone are the Guernsey networks named in travel-eSIM providers’ published network details. That creates a choice beneath the eSIM, although travellers do not usually select the operator directly. Instead, the provider’s own network listing determines which operator is associated with the eSIM you buy. Checking that pairing in advance can therefore tell you more about the intended local connection than the eSIM brand alone; it is not something you need to discover after arriving.

Are there any free data eSIM plans available for Guernsey?

A zero-cost data option is listed for Guernsey, but it is a small trial allowance rather than a usable holiday plan. It is generally conditional on registering with the provider and may be limited to one per customer. That makes it useful for getting online briefly after arrival or checking coverage, but not for normal mobile use throughout a visit. Guernsey has broad eSIM availability, yet free data remains an exception rather than the standard offer.

Are there any unlimited data eSIM plans available for Guernsey?

Many major travel eSIM brands include an unlimited option for Guernsey, so this is a crowded part of the market. The catch is that “unlimited” means access continues after the fast-data allowance is used, but at reduced speed; depending on the plan, normal speeds return each day or remain restricted for the rest of the plan. That can make video difficult and maps slower. Compare the allowance and reset terms rather than relying on the label.

eSIM Providers for Guernsey

Sure Mobile and Vodafone are the main stated network options, but the market is not evenly spread: most eSIMs list just one operator, while eSimCard lists more than one. That distinction matters in practice. A single-network plan leaves you with that operator wherever you travel; a multi-network plan gives you another listed option if one is weaker at your stop. Check the network names before choosing.
