Best eSIM for Puerto Rico

Before you spend a cent: if you are flying in from the mainland United States, you almost certainly do not need a travel eSIM for Puerto Rico at all. The island is a US territory, and AT&T, T-Mobile and Verizon all treat it as domestic on their standard plans, so your handset finds a network on the taxiway and your allowance behaves exactly as it does in Ohio. Nobody selling eSIMs is going to volunteer that, so we will. This guide is written for everyone else, the visitors arriving from Madrid, Toronto, Bogota, London and Sao Paulo, for whom Puerto Rico is emphatically abroad and roaming is emphatically billable. If that is you, the decision is really about which local network your plan lands on, because Airalo rides T-Mobile, Holafly rides Claro and Nomad rides Liberty, and those three are not equally good in the same parts of the island.

Quick Pick: the Best eSIM for Puerto Rico

Airalo (20 GB / 30 days): Rides T-Mobile, which swept every speed award and took 12 of 15 outright wins in Opensignal's June 2026 island report, and metered plans suit a trip that is mostly San Juan, beaches and a rental car on the coastal ring.

Airalo Puerto Rico Plans

Airalo sells its island product under the Boricua Mobile label and puts it on T-Mobile, which is the correct call given what the measurement data says. T-Mobile took twelve of the fifteen outright awards in Opensignal's June 2026 Puerto Rico report, swept all four speed categories, and posted the strongest reliability score of the three operators. For the visitor whose week is Condado, Old San Juan, a rental car along PR-52 and a couple of beach days, that is the network you want underneath you.

Pricing starts near four dollars for a small plan and rises to roughly 35 dollars for 20 GB over thirty days, with unlimited options running from about 18.50 to 99 dollars depending on how long you need them. Be aware that the unlimited tiers give you a few gigabytes of full-speed data per day before dropping to a throttled trickle, which is fine for maps and messaging and irritating for anything else. A 5 GB or 10 GB metered plan is the sweet spot for a normal week, given how freely San Juan hotels and cafes hand out WiFi.

Holafly Puerto Rico Plans

Holafly connects to Claro, the operator Opensignal placed first for coverage on the island and the one whose 5G build is measured against territory rather than headcount. That distinction is the whole argument for paying more here. Roughly 95 percent of the land area starts to matter when your plan includes the Ruta Panoramica, the ridges around Jayuya and Adjuntas, an early start into El Yunque, or a ferry across to Vieques where the paved roads run out quickly.

Pricing runs from about 18.90 dollars for three days to around 106.50 for a full month of unlimited data, which is a lot more than a metered island plan costs and buys you the right not to think about it. Two caveats before you commit. Sharing is capped at roughly a gigabyte a day, so this is a poor choice for a family trying to run four devices off one handset. And it is data only, with no Puerto Rico number attached, so anything expecting an SMS code needs another route.

Nomad Puerto Rico Plans

Nomad puts its island plans on Liberty Puerto Rico, the network AT&T customers used to sit on before Liberty Latin America bought the business outright at the end of 2020. The towers did not move. What changed is the badge, the investment programme and the trajectory: Liberty added a hundred points to its Opensignal reliability score in a single year, the largest jump any operator on the island recorded, and it won the Video Experience award outright on 69.8 points.

The pricing is the reason to look. A gigabyte over seven days is about 4.50 dollars, 5 GB over thirty days is around 15, 10 GB is roughly 25 and the 50 GB tier lands near 49, which is an unusually flat curve as the plans get bigger. There is no unlimited option, and the plans are documented as LTE rather than 5G, so treat this as the sensible metered choice for a city-and-beach trip rather than the one to take up a mountain.

Mobile Networks in Puerto Rico

Three operators run their own infrastructure here: Claro Puerto Rico, part of America Movil, Liberty Mobile, the Liberty Latin America business that directly succeeded AT&T on the island, and T-Mobile, which folds Puerto Rico into its national footprint rather than running it as a foreign market. Opensignal's June 2026 report split the honours in a way that maps unusually neatly onto how people travel. T-Mobile took 12 of the 15 outright awards, swept every speed category, and recorded an average download of 119.5 Mbit/s against 15 Mbit/s up. Claro took the coverage ranking. Liberty won Video Experience on 69.8 points out of 100, ahead of Claro on 66.2 and T-Mobile on 63.8.

Claro is the network to want if your Puerto Rico is bigger than the hotel beach. Its 5G already reaches roughly 95 percent of the territory of the island rather than 95 percent of the people, which is a far harder target on a landmass with a mountain range running down the spine of it. The company has committed up to 500 million dollars over three years to fibre and 5G modernisation, about 150 million of that falling inside 2026, and it presents a large share of that as hurricane resilience work, which on this island is not a marketing line. T-Mobile is the speed and dependability leader, scoring 935 out of 1,000 on Opensignal's Reliability Experience measure, ten points clear of Liberty, and it is genuinely excellent across the San Juan metro, Ponce, Mayaguez and the coastal highway ring. Liberty Mobile inherited AT&T's towers when Liberty Latin America closed a 1.95 billion dollar purchase of the wireless and wireline business in Puerto Rico and the US Virgin Islands at the end of October 2020, spent around 70 million integrating it, and retired the AT&T brand here in September 2021. It is solid through the urban belt and it is improving faster than either rival, having added 100 points to its reliability score in twelve months.

How to Choose the Right Plan

Start with the question almost nobody asks first: are you actually a customer? If you hold a standard American postpaid plan, this island is domestic territory and you should skip every product on this page and spend the money on mofongo instead. Everyone else, sort the decision by geography. A trip that lives in San Juan, Condado, Isla Verde and a rental car on the coastal highways should take Airalo on T-Mobile, the network that swept the 2026 speed awards, and a 5 GB or 10 GB plan will cover a week comfortably given how much hotel and cafe WiFi you will pass through. A trip that climbs into the Cordillera Central, spends a full day in El Yunque or crosses to Vieques and Culebra should pay the premium for Holafly on Claro, whose coverage is built against land area rather than population. Nomad on Liberty is the value middle, and its 20 GB and 50 GB tiers are the cheapest way to cover a long stay if you are staying near the coast. Whichever you buy, download offline maps of the interior and the two outer islands before you leave the metro, because no plan sold anywhere fixes a ravine under a rainforest canopy.

Frequently Asked Questions

I have an American phone plan. Am I buying anything for this trip?

On a standard postpaid plan from AT&T, T-Mobile or Verizon, no. Puerto Rico is a US territory and all three bill it as domestic, so calls, texts and data draw on the same allowance you use at home with no roaming charge attached. T-Mobile operates its own towers here, AT&T customers ride Liberty's network since Liberty Latin America bought that business in 2020, and Verizon has no island network of its own so it roams onto local partners. The exceptions worth checking are budget prepaid brands and MVNOs, some of which cap or meter domestic roaming, so read your plan's roaming clause rather than assuming.

Coming from Europe or Canada, which network should my eSIM be on?

It depends on the shape of the trip rather than the size of the plan. If your week is San Juan, the beaches and a rental car on the coastal ring, take T-Mobile through Airalo, because it is the fastest and most reliable network on the island by a clear margin. If you are heading into the Cordillera Central, spending real time in El Yunque, or crossing to Vieques or Culebra, Claro through Holafly is the safer footprint because its build is measured against territory rather than population. Liberty through Nomad sits between the two and prices well for a metered plan.

Does a plan sold as a United States eSIM cover the island?

Usually, but not universally, and the wording on the product page is what settles it. Some providers fold the territory into their US coverage silently, some sell a separate island plan, and a handful of cheaper regional products quietly stop at the fifty states. Airalo, Holafly and Nomad all list a distinct Puerto Rico plan, which is the simplest way to remove the ambiguity. If you are visiting the mainland and the island on one trip, check that both appear by name in the coverage list before you pay, because discovering the gap at baggage reclaim is an expensive way to learn it.

Will I have signal in El Yunque and out on Vieques?

Partially, and the pattern is predictable enough to plan around. In El Yunque the PR-191 corridor and the visitor areas hold a signal, while the canopy and the ravines on the La Mina and Mount Britton trails will take it away from you within a few minutes of walking. On Vieques and Culebra the settlements are covered, so Isabel Segunda, Esperanza and Dewey are fine, but the beaches most people cross for, Playa Negra and Zoni among them, often are not. Download your offline maps in San Juan and treat any bars you find out there as luck.

Would a local Claro or Liberty prepaid card be cheaper than an eSIM?

Almost never for a holiday. Local prepaid here is priced for residents on monthly cycles, so the entry point is roughly 18.99 dollars at Claro and about 25 dollars at Liberty before you have added anything, and airport counters sell visitor bundles from around 15 dollars for 3 GB. Set that against roughly 4 dollars for a small Airalo or Nomad plan and the arithmetic runs the opposite way from most countries we cover. A local card starts making sense at a month or more, or if you specifically need an island phone number.

Can I keep using the same plan in the US Virgin Islands or the Dominican Republic?

Not on a Puerto Rico plan. St Thomas and St Croix are a separate US territory with their own coverage listing, and the Dominican Republic is a different country entirely, so an island-only eSIM stops when the ferry or the short hop does. American postpaid customers are in a better position here, since the US Virgin Islands are normally bundled into the same domestic footprint as Puerto Rico. Everyone else island-hopping through the northern Caribbean should buy a regional or global plan that names each stop rather than stacking single-island purchases.
