Top 10 eSIM providers for San Juan in 2026
Airalo is our pick for most visitors to San Juan in 2026. Its Puerto Rico plans start at $4.00, activate by QR code before you fly, and work from Isla Verde to Condado. What pushes it past Saily and Holafly's pricier unlimited plans is price per GB, backed by fewer hidden-fee reports than either rival.
The ranking weighs three things, in this order. Network quality comes first, judged where visitors spend their days in San Juan, from the cobbled lanes of Viejo San Juan to the hotel towers along Isla Verde. Price per GB comes second, and Airalo currently has the lowest price per GB among the app-based providers. Activation ease comes third, because scanning a QR code at home in Chicago or Toronto beats waiting in line at a phone store in Hato Rey. Providers lose points where Trustpilot reviewers report top-up surprises or throttling the checkout page never mentioned. Signal inside the thick stone walls of Castillo San Felipe del Morro tends to fade on every network, so download tickets and offline maps before you cross the grassy esplanade.
The most common mistake is buying a roaming eSIM at all. Puerto Rico is a U.S. territory, so travellers from the mainland on a T-Mobile, AT&T or Verizon plan usually get domestic service with no roaming charge. A second mistake is waiting until the arrivals hall at Luis Muñoz Marín International Airport (SJU) to sort out data, because the terminal Wi-Fi can be slow at peak hours and the ride to Condado takes roughly 15 to 20 minutes. A third is assuming the Tren Urbano covers the tourist core: its 16 stations run from Bayamón to Sagrado Corazón in Santurce, and none reach the old walled city, so you'll rely on ride-hail apps more than you might expect. The Cataño ferry often drops to one bar halfway across San Juan Bay, so take a screenshot of the return schedule before boarding.
Airalo is not the right pick if you're renting in Ocean Park or Miramar for a month. San Juan rates 7.8/10 for digital-nomad suitability (sourced from TTDI's editorial rubric), and remote workers here tend to burn through data on video calls faster than a fixed-size plan allows. For a 30-day stay, a Claro or Liberty prepaid line with a Puerto Rican number will likely cost less per GB, and the local number earns its keep in other ways: restaurant bookings and delivery apps both expect a 787 or 939 area code. Airalo also requires an unlocked, eSIM-capable phone, so anyone carrying an older or carrier-locked handset should plan on a physical SIM from a shop on Avenida Ponce de León.

The full list
-
Airalo
Airalo installs by QR code, so the eSIM can be live before you reach the taxi rank in Carolina, and speeds hold up well along Ashford Avenue in Condado. Its Puerto Rico tiers run up to a $50.00 plan for heavy users, and reviewers rarely report fees beyond the listed price.
-
Saily
Saily, from the team behind NordVPN, activates inside its app and includes built-in ad blocking, a real advantage on the open Wi-Fi at cafes around La Placita de Santurce. Its price per GB tends to sit close to Airalo's, though it offers fewer plan sizes for Puerto Rico.
-
Nomad
Nomad often runs sales that undercut rivals on mid-size plans, a sensible fit for a week split between Isla Verde beach days and the forts. Activation is by QR code, and its data tends to hold signal along the Piñones coastal road east of the city.
-
Holafly
Holafly sells unlimited-data plans, handy for tethering a laptop in a Condado hotel or streaming music on the drive to El Yunque. The catch: a fair-use throttle, hotspot limits that reviewers flag, and a per-day cost well above Airalo's on short trips.
-
Maya Mobile
Maya Mobile offers unlimited plans with a clearer high-speed allowance than most, plus hotspot sharing that works well for a group renting an apartment off Calle Loíza in Santurce. Activation is a QR code emailed at checkout.
-
Ubigi
Ubigi, run by Transatel, is a sensible fallback for travellers connecting through Miami or Orlando, since some of its USA plans also list Puerto Rico, so check the coverage page before buying. Signal near the cruise piers in Old San Juan is reliable, but its price per GB sits mid-pack.
-
Claro Puerto Rico prepaid
Claro runs one of the largest networks on the island, and its signal holds furthest inland, which pays off on a day trip to El Yunque or the Bacardí distillery in Cataño. To get set up, visit a store (Plaza Las Américas in Hato Rey is one option) and bring an unlocked phone.
-
Yesim
Yesim activates by QR code and suits a weekend in the guesthouses of Viejo San Juan, though reviewers note that its Puerto Rico data sometimes routes through U.S. partner networks, so video calls from a Calle Fortaleza balcony can feel slightly laggy.
-
Mint Mobile
Mint Mobile runs on T-Mobile, which operates its own towers in Puerto Rico, and Mint has treated the island as domestic coverage, so confirm that on its coverage map. A multi-month plan can double as a local line for a long Miramar stay, though signup requires a U.S. address.
-
GigSky
GigSky's in-app activation takes a few minutes, which makes it a reasonable fit for the cruise-stopover crowd with one afternoon between the piers and Paseo de la Princesa. Its per-GB pricing for Puerto Rico tends to run above the leaders.
