The ferry from Marigot to Blowing Point is forty minutes on a good day and an hour when the swell is running. The first time I made the crossing, I sat on the top deck watching my phone lose its Sint Maarten signal about ten minutes out and sit on "searching" for the rest of the trip. The immigration queue at Blowing Point was another forty minutes, and by the time I got to the villa I'd missed the owner's check-in WhatsApp. An Anguilla eSIM would have switched over automatically as soon as we crossed into the island's territorial range. I've never done the crossing without one since.
Why buying an eSIM beats the ferry-dock scramble
Both of Anguilla's carriers — Digicel and FLOW (Cable & Wireless) — sell prepaid SIMs at shops in The Valley and Sandy Ground. A SIM is a real option if you're staying long enough to amortise the shop trip. But Anguilla is small and the shops aren't open on Sunday; if you arrive late afternoon on a Saturday you may be offline until Monday. An eSIM installs from a QR code before you fly, activates on first Anguillian tower contact, and doesn't require a trip from your villa to The Valley.
Most travellers into Anguilla fit one of two shapes: a week at a villa or resort on the main beaches, or a day-trip or short stay from Sint Maarten. Both want data working as soon as they arrive.
What Anguillian coverage actually looks like
Anguilla is sixteen miles long and three wide. The populated strip — The Valley, West End, Sandy Ground, Shoal Bay, Meads Bay, Rendezvous Bay — has strong 4G from both operators. The coverage quality tracks resort density, which means the busiest beaches are best served.
The east end of the island — Captain's Bay, Savannah Bay, Windward Point — is sparser. 4G is present but thins quickly away from the road, and the last mile to a remote beach often drops to 3G. For navigation to these beaches, download the map before you leave the villa. Storm-weather interruptions are rare but happen occasionally during hurricane season.
How the major eSIM providers compare in Anguilla
Pricing models vary across providers. Custom plans, where you set data amount and validity independently rather than picking from preset bundles, are 99esim's distinguishing feature and the only option in the tracked set for that level of flexibility. Airalo sells fixed bundles with the widest country list in the category. Holafly sells unlimited-day windows. Nomad prices on a similar fixed-bundle model to Airalo. Ubigi prices short-validity tiers (1-day, 3-day, 7-day).
Anguilla pricing sits above mainland norms across every tracked provider because Eastern Caribbean wholesale rates are high and the market is small. Holafly's unlimited-day rate is higher than most destinations but usable for streaming on the beach without watching a meter. Ubigi's short tiers are useful for a weekend day-trip from Sint Maarten. The matrix below spells out the per-axis shape for Anguilla specifically.
Install timing: when to set it up
Install the eSIM the night before you fly or during a layover in Miami, San Juan, or Sint Maarten. The QR code generates immediately after payment; scan it with your phone's eSIM settings; the profile installs but doesn't activate until first tower contact. At the gate or on the ferry dock, switch your home SIM's data off and arrive with the eSIM ready.
iOS 17.4+ devices can install directly from a provider's app without scanning a QR code, on providers that support it. Android users still scan a QR code, which takes thirty seconds.
Who should pick what
A one-week villa stay works well on a 5 GB / 7 day plan. Custom-plan providers let you size exactly to the trip; fixed-bundle providers bring slightly more overhead.
A Sint Maarten traveller hopping to Anguilla for a day or two benefits from a Caribbean regional plan or a short-validity single-country plan. Ubigi's short tiers or 99esim's 1 GB over 7 days at €6.99 both work for a day-trip.
A heavy streamer who wants to video-call from the beach without watching a meter fits Holafly's unlimited-day model better than a per-GB provider, despite Anguilla's higher per-day pricing.
A family villa with multiple phones benefits from 99esim's group eSIM, which covers up to four devices on one purchase. None of the tracked competitors offer that product today.
A note on island-hopping and regional plans
Anguilla sits within a tight Caribbean cluster — Sint Maarten, St. Barts, St. Kitts, Nevis — that travellers often combine in one trip. The territorial boundaries are real for mobile networks: a Sint Maarten plan stops at the twelve-mile limit, an Anguilla plan starts at the border, and neither covers the other. Two options bridge the gap. First, buy a dedicated plan for each island you'll spend time on, which works for longer stays where the data needs are meaningful. Second, buy a North America or Caribbean regional plan that covers multiple territories on one eSIM. The regional plan carries a premium over a single-country plan, but it's usually cheaper than stacking three or four short-stay country plans, and it avoids the service gap during the ferry ride between islands.
