About this eSIM

Puerto Rico feels familiar to a lot of visitors and then quietly is not, and connectivity is one of the places that shows. The metro area around the capital is thoroughly wired; the mountainous middle and the smaller islands are a different story, and the grid that powers the towers is less dependable than the towers themselves. An eSIM gives you a line that works from arrival without touching your home plan.

Getting online when you land

Install before departure while you have wifi, then enable the line once you are on the ground at Luis Muñoz Marín. It usually attaches during the walk to baggage claim.

Getting out of the airport is where it pays off. Ride hailing runs from a designated pickup area, and rental car counters are off site with shuttle pickups that are much easier to find when you can see them on a map. If you are heading straight to the west coast or the mountains, this is also the moment to check road conditions, since a lot of the interior driving is slow and the estimate you get at the airport is the honest one.

The networks you'll be on

Coverage here comes via Claro, running 4G LTE and 5G where it has been rolled out. For practical travel the generation does not matter much: LTE in the metro handles navigation, calls, streaming and uploads without fuss. In the mountains and on the smaller islands you will see 3G or nothing, and the difference is usually terrain rather than technology.

Worth saying plainly: the island's electricity supply is unreliable and outages are common. Extended power cuts affect network sites as well as your hotel, so a strong signal one hour is not a promise of a strong signal the next. Treat data as excellent but not guaranteed, and keep things saved locally.

Where coverage holds, and where it thins

The San Juan metro is the strong zone: Old San Juan, Condado, Santurce, Isla Verde and out through Carolina and Bayamón are all well covered. The main highways are reliable too, including the runs east toward Fajardo, west toward Aguadilla and south over the mountains to Ponce, though the descent through the cordillera has spots where you lose it.

The interior is where it gets thin. El Yunque has coverage at the entrance area and near the road, and much less on the trails and at the waterfalls below the canopy. The mountain towns of the Cordillera Central, Jayuya, Adjuntas, Utuado and the karst country around them, have service in town and long gaps on the winding roads between. The Camuy cave system is offline underground, as caves are.

Offshore, Vieques and Culebra have coverage around the settlements and the main roads, weaker on the remote beaches, and the ferry crossings from Ceiba drop out mid channel. Bioluminescent bay tours run at night in mangrove channels where you should not expect anything at all, which is fine, because the point is to look at the water rather than your phone. Rincón and Cabo Rojo are connected in town and patchier along the cliffs and salt flats.

What you'll actually use data for here

Driving is the main one. You will almost certainly rent a car, because the bus network does not go where you are going, and navigation across an island where road numbers repeat and mountain routes double back is where your data earns its keep. Live traffic around the metro is genuinely useful, since the highways there congest hard.

Ferry reservations to Vieques and Culebra are a second: they are booked online, they sell out, and the schedule shifts with weather. Then hurricane and storm tracking during the season, beach and surf conditions on the west coast, and restaurant hours, which change more than published listings suggest, so a quick message or check before driving forty minutes to a place is worth the effort.

Before you fly

Get the eSIM installed at home and make it your data line while your usual SIM stays in for bank verification texts. Toggle roaming on for the travel line only.

Download offline maps for the whole island, not just the metro, because the interior is exactly where you will lose signal and exactly where the navigation matters. Save ferry bookings and accommodation addresses as screenshots. Carry a power bank and charge it whenever you have power, given how ordinary outages are. And if you are staying somewhere rural, ask your host how they handle blackouts before you need to know; the answer tells you a lot about how the week will go.

Before you buy

Important to know

This is a data-only eSIM. It carries no calls or SMS on its own number.
Your existing number stays on your primary SIM, so calls and verification texts keep working.
Your phone must support eSIM, and some carrier-locked phones cannot install one.
Signal varies with location, terrain, congestion and your handset. Dense urban areas are consistently better served than remote ones.
5G only works where the host network has deployed it and your phone supports it. Everywhere else it falls back to 4G LTE.
The eSIM selects a host network automatically. You cannot pick or switch between them.

Frequently asked questions

Does an eSIM work in Puerto Rico?

Yes. Your Puerto Rico eSIM connects automatically the moment you arrive, with no roaming fees and nothing to set up at the airport. The host networks it can use are AT&T. Coverage runs on 4G LTE and 5G where the network has rolled it out, and falls back to 4G elsewhere.

Do I get 5G in Puerto Rico?

Yes, where it has been deployed. 5G runs on AT&T in Puerto Rico, and your eSIM uses it automatically on a 5G-capable phone, dropping back to 4G LTE outside covered areas. No country is covered everywhere, so 5G availability varies by location.

Which mobile network does a travel eSIM use in Puerto Rico?

This eSIM connects only to Claro, the island's largest telecoms company. Claro started out as the Puerto Rico Telephone Company and has been owned by América Móvil since 2007. It runs 4G and 5G, but there's no second network to fall back on, so in the mountains and on Vieques or Culebra expect gaps.

Are power cuts common in Puerto Rico?

Yes. LUMA Energy runs the grid and Genera PR runs the power plants. In 2025, LUMA reported that outages were lasting 12% longer than the year before. Long power cuts can also affect phone masts, so carry a charged power bank and download offline maps. If you're staying somewhere rural, ask your host about backup power.

Where can I get hurricane alerts in Puerto Rico?

Use the National Weather Service office in San Juan (weather.gov/sju). It publishes tropical outlooks, warnings and marine forecasts for Puerto Rico and the US Virgin Islands, and posts updates on X and Facebook. Wireless Emergency Alerts are sent to phones as well, so keep emergency alerts switched on. The Atlantic hurricane season runs from June to November.

What happened to Puerto Rico's phone and internet after Hurricane Maria?

Hurricane Maria in September 2017 knocked out power across the island and largely destroyed its internet infrastructure. In 2019 the FCC committed $950 million to rebuilding and strengthening networks in Puerto Rico and the US Virgin Islands. The networks have been rebuilt since, but a major storm can still cut both power and signal.

How much data do I need for 7 days in Puerto Rico?

For 7 days in Puerto Rico, Viasimo sells 1 GB for $3.59. Our sizing recommendation, not a measurement: maps, messaging and the occasional lookup, about 1 GB a week; maps, social, photos and some browsing, about 3 to 7 GB a week. The data calculator on this site works it out from how you actually use your phone.

Know before you go

Puerto Rico: what to know before you land

In Puerto Rico this eSIM runs on Claro, the island's largest telecoms provider, which grew out of the old Puerto Rico Telephone Company. The power grid is the main risk to staying connected. Outages have increased since private operators took it over, so pack a power bank and bookmark NWS San Juan before hurricane season.

Claro and the old Puerto Rico Telephone Company

Claro is the largest telecoms provider in Puerto Rico, and its history explains its reach. It began in 1914 as the Puerto Rico Telephone Company and was owned at different times by ITT, the Puerto Rican government, GTE and Verizon. Verizon agreed to sell it to Mexico's América Móvil in 2006, and the deal was completed in March 2007. The business was renamed Claro in stages, finishing in 2013, and Verizon's old CDMA network was switched off by 2014.

Your eSIM connects only to Claro. It's the island's long-established network and runs 4G and 5G. Where Claro has switched on 5G and your phone supports it, you'll use 5G. Elsewhere, including the Cordillera Central and the smaller islands, you'll be on 4G or slower.

With only one network, you can't switch to another operator if you lose signal. If your data stops working in the mountains, try turning airplane mode on and off, then wait until you're back in a town such as Utuado or Adjuntas.

Power cuts, LUMA and Genera PR: keeping your phone charged

Puerto Rico's electricity system is the weak link in staying connected. Since June 2021, LUMA Energy has run transmission and distribution under a 15-year contract, and since July 2023 Genera PR, a subsidiary of New Fortress Energy, has operated the power plants that used to belong to PREPA. Outages haven't gone away. In 2025 LUMA reported that the average length of outages had risen by 12% and their frequency by 2% compared with the year before, partly because of a funding dispute with PREPA. In September 2021, plant failures led to four days in a row of rolling blackouts.

This affects more than your hotel room. Mobile phone masts need electricity too, and after Hurricane Maria in 2017 the island's internet infrastructure was largely destroyed. In a long power cut, signal can weaken even where coverage is normally good.

Carry a fully charged power bank, and recharge it whenever you have power. Download offline maps of the whole island. If you're staying in the countryside, ask your host whether they have a generator or solar backup and how they keep wifi running during an outage.

Hurricane and marine alerts from NWS San Juan

The US National Weather Service office in San Juan (weather.gov/sju) covers Puerto Rico and the US Virgin Islands. It publishes tropical outlooks and storm reports during the Atlantic hurricane season, which officially runs from 1 June to 30 November, as well as hourly local forecasts, warnings, and marine and beach forecasts. Check the marine and beach forecasts before taking the ferry to Vieques or Culebra, or going surfing at Rincón.

NWS also sends Wireless Emergency Alerts through the mobile networks. Before you travel, check that emergency alerts are switched on in your phone's notification settings. NWS San Juan posts updates on X and Facebook, and following either account in your browser gives you a second source of updates.

If a storm is on its way, use your data while you still have power and signal. Message home to say where you'll be staying, download offline maps, and screenshot your flight, ferry and accommodation details. After Hurricanes Irma and Maria in 2017, the whole island lost power, so prepare as though both power and signal could go down for a while.

7-day itinerary

Seven days in Puerto Rico: Old San Juan, El Yunque, Culebra, Ponce and Rincón

A driving week around the island: Old San Juan's forts, the El Yunque rainforest and a bioluminescent lagoon in the east, a ferry day to Culebra, then south to Ponce and west to Rincón before returning along the north coast.

Length: 7 days
Bases: 4

When to go December to April is driest and least humid, though busiest; the Atlantic hurricane season runs from 1 June to 30 November, peaking from August to October, when ferries and power can be disrupted.

Day 1 San Juan

Old San Juan's streets and squares

Luis Muñoz Marín Airport is about 20 to 30 minutes from Old San Juan by taxi or Uber.

Walk the blue cobblestone streets of Old San Juan from the Plaza de Armas to the Cathedral of San Juan Bautista, where Ponce de León is buried. Continue to La Fortaleza, the governor's residence, seen from its gate, and down to the Paseo de la Princesa along the city walls. End the day in the small squares around Calle San Sebastián and the Plaza de Colón.

Signal Claro 4G and 5G across San Juan. Power cuts can affect masts, so carry a charged power bank from day one.
Day 2 San Juan

El Morro, San Cristóbal and Santurce

Visit Castillo San Felipe del Morro on the headland at the mouth of the harbour, part of the San Juan National Historic Site and a UNESCO site, then walk along the coast to Castillo San Cristóbal, the larger fort guarding the land approach. In the afternoon, visit the Museo de Arte de Puerto Rico in Santurce and see the street murals on Calle Cerra. Spend the evening at La Placita de Santurce.

Signal Strong Claro coverage at both forts and in Santurce. Inside the thick fort walls and tunnels the signal drops.
Day 3 Fajardo

El Yunque and the Fajardo bioluminescent lagoon

San Juan to El Yunque is about 45 minutes to 1 hour; Luquillo and Fajardo are each 20 to 30 minutes further.

Drive east to El Yunque National Forest, the only tropical rainforest in the US National Forest System. Climb the Yokahú Tower, stop at La Coca Falls and walk a trail such as Juan Diego or La Mina if open; check the forest's website for trail status and entry reservations. Spend the afternoon at Luquillo Beach and its roadside food kiosks. After dark, kayak through the mangrove channel into Laguna Grande, where microorganisms glow when the water moves.

Signal Claro 4G is good in Luquillo and Fajardo but patchy on the El Yunque road and weak or absent on the forest trails. Phones should stay in a dry bag on the kayak trip.
Day 4 Fajardo

Culebra and Flamenco Beach

Ferries leave from Ceiba, near Fajardo, and take about 45 minutes to 1 hour 30 minutes depending on the boat. Buy tickets in advance online and check the marine forecast; sailings are cancelled in rough seas.

Take the early ferry to Culebra, a small island off the east coast. Ride a público or golf cart to Flamenco Beach, a long curve of white sand with clear water and an old rusted tank left from US Navy training. Snorkel at Carlos Rosario or Tamarindo, where turtles are often seen, then take the afternoon ferry back to the mainland.

Signal Signal comes and goes on the ferry. Culebra has Claro coverage in Dewey and at Flamenco Beach, but it is slower than on the mainland and weaker on the far beaches.
Day 5 Ponce

Ponce, the Pearl of the South

Fajardo to Ponce is about 2 hours 15 minutes to 2 hours 30 minutes via the PR-52 toll road. Buy or activate an AutoExpreso toll tag with your hire car.

Drive across the island to Ponce. Walk the Plaza Las Delicias to see the red-and-black striped Parque de Bombas, an old firehouse, and the Cathedral of Our Lady of Guadalupe. Visit the Museo de Arte de Ponce, one of the Caribbean's main art museums, then climb to Castillo Serrallés, the former home of a rum-making family, and the cross-shaped viewing tower La Cruceta del Vigía above the city.

Signal 4G and 5G in Ponce. The PR-52 has good coverage, with a few weaker spots as the road crosses the Cordillera Central.
Day 6 Rincón

Hacienda Buena Vista and Rincón

Ponce to Hacienda Buena Vista is about 20 minutes; Ponce to Rincón is about 1 hour 45 minutes by road.

Visit Hacienda Buena Vista in the hills north of Ponce, a restored 19th-century coffee and maize plantation with working water-powered machinery; book the guided tour in advance. Then drive west along the south coast to Rincón on the island's western tip. Watch the sunset from the Punta Higüero lighthouse park, a viewpoint for humpback whales in winter and surfers year round.

Signal Weak signal in the hills around Hacienda Buena Vista. Claro 4G returns along the south coast and in Rincón.
Day 7 San Juan

Cueva Ventana and back to San Juan

Rincón to Arecibo is about 1 hour 15 minutes; Arecibo to San Juan airport is around 1 hour 15 minutes on the PR-22.

Drive along the north coast to Arecibo and take a guided tour to Cueva Ventana, a limestone cave whose opening frames the Río Grande de Arecibo valley. Stop at the Pozo de Jacinto blowhole or the beaches at Isabela if time allows, then continue east to San Juan. Leave plenty of time for the airport road traffic before an evening flight.

Signal Good 4G along the PR-22 and in Arecibo. Inside Cueva Ventana there is no signal.

Staying connected on this route

Your eSIM uses Claro only; if data stops in the mountains, toggle airplane mode and wait rather than looking for another network.
Carry a charged power bank every day: power cuts are common and can also weaken mobile masts.
Check NWS San Juan's marine forecast before the Culebra ferry and keep your ferry tickets saved offline.
Turn on emergency alerts in your phone settings so National Weather Service warnings reach you.
