Best eSIM for Puerto Rico

Puerto Rico catches travellers out. It is a United States territory using US mobile networks, so American visitors arrive and notice nothing at all — but anyone flying in from India, the UK, Europe or Latin America is roaming internationally the moment they land at Luis Muñoz Marín (SJU), on some of the least forgiving rates around. The trip itself is data-hungry: a hire car is close to essential, and the drive from San Juan out to El Yunque, down to Ponce or west to Rincón runs on live navigation. Add ferry times for Vieques and Culebra, which change, and restaurant hunting in Santurce, and the phone rarely gets a rest. A travel eSIM sidesteps the roaming bill entirely. See the plans above.

Most stays run five to eight nights, often a long weekend from the mainland or a stop on a Caribbean itinerary, so match validity to that rather than buying a month. Data use is heavier than a typical island trip because of the driving: continuous navigation on the highways around San Juan, plus streaming on the road and photo uploads from the beaches. 5G is widely available in the San Juan metro area and along the north coast, so a plan that includes it is genuinely useful here. Hotspot matters if you are working remotely, which many visitors do from Old San Juan. You do not need a Puerto Rican number for car hire, ferries or apps. If your trip also takes in the mainland, a separate United States plan or a wider North America regional plan may suit better. Check your phone on the device page.

Puerto Rico is served by the same kind of networks as the mainland — Claro Puerto Rico, Liberty Mobile and T-Mobile — and your eSIM connects to whichever partner network is strongest. Coverage on the island is good by Caribbean standards, with 5G across the San Juan metro area. The weak spots are inland and upland: the rainforest trails in El Yunque, the karst country around Arecibo and the mountain roads of the Cordillera Central.

• San Juan — the fastest data on the island, including Old San Juan and Condado
• Ponce and Mayagüez — reliable service in the south and west
• El Yunque — signal at the entrance, dropping away on the trails
• Vieques and Culebra — usable in the towns, patchy on the ferry crossing

If you are flying in from outside the United States, the eSIM is the straightforward way to avoid an international roaming bill on a driving holiday. A local prepaid plan is built around monthly cycles and rarely fits a week. Visitors from the US mainland usually need nothing extra.

1. Buy the plan above; the QR code arrives by email in minutes.
2. iPhone on iOS 17.4 or later: tap the install link. Otherwise Settings, then Mobile Data, then Add eSIM.
3. Android: Settings, then Connections or Network, then SIM manager, then Add eSIM, then scan the QR code.
4. Label the line Puerto Rico so it is easy to identify.
5. Turn Data Roaming on for the eSIM line and mobile data off on your home SIM, which stays active for calls and OTPs.
6. On landing at Luis Muñoz Marín, select the eSIM as your data line before you collect a hire car. Validity begins at that first connection, not at purchase.

Install at home on Wi-Fi a few days before you travel and leave the line switched off. The plan starts only when the eSIM first connects to a network in Puerto Rico, so early installation is free. If you are connecting through Miami, New York or another mainland airport, keep the eSIM disabled there — a Puerto Rico plan is not the same as a mainland United States plan.
