San Juan eSIM
29 Puerto Rico plans · from $4.12
San Juan is Puerto Rico's capital and almost every visitor's first stop — a travel eSIM activates the moment you land, and coverage across the metro area from Claro, T-Mobile and Liberty is as strong as anywhere in the Caribbean. No passport needed if you're flying in from the US mainland; the eSIM question is a separate one from the entry question.
Landing at Luis Muñoz Marín International Airport (SJU)
About 8km from Old San Juan — a travel eSIM is live well before you clear the taxi or rideshare line, no SIM kiosk required.

How “Unlimited” works: Never cut off — each plan gives a set amount of full-speed data, then a slower speed. The exact allowance and speed are shown on every plan.Read more
Unlimited plans never run out and your eSIM is never disconnected, but every one has a fair-use limit: a set amount of full-speed data, after which the speed is reduced. The amounts differ between plans — most give a daily full-speed allowance that refills every 24 hours from when you first activate the eSIM, while Premium plans give a larger allowance for the whole plan instead. Each plan states its own allowance and the speed after it before you buy. At the reduced speed, messaging, maps, email and light browsing still work; video streaming and video calls may not. If you want every gigabyte at full speed, choose a fixed-GB plan.
Which networks you'll be on in San Juan
Siima eSIMs for Puerto Rico ride Claro, T-Mobile or Liberty, whichever is strongest where you are. All three hold up well across San Juan itself — the differences mostly show up once you head into the island's interior.
Coverage around San Juan
Old San Juan
Strong 4G/5G across the Spanish colonial old town, including both UNESCO-listed forts, Castillo San Felipe del Morro and Castillo San Cristóbal.
Condado and Isla Verde beaches
Full coverage along the main beachfront hotel strip, a short ride from the airport.
Metro San Juan and Río Piedras
Consistent signal through the wider metro area, including the university district.
Heading out of the city
Coverage holds up well toward El Yunque and Ponce — see the Puerto Rico guide for the island's real connectivity risk, which is power-grid outages rather than signal gaps.
How much data you need
A couple of days in San Juan runs 1-2 GB. Add 2-3 GB if El Yunque or a day trip further out is on the itinerary, and budget separately for a Vieques or Culebra ferry crossing.
