How to install your Puerto Rico eSIM in 3 steps
Setting up your Puerto Rico eSIM takes only a few minutes and can be done before you even board your flight to San Juan.
- Buy and receive your QR code. Pick a plan sized for your trip - from a 1GB/7-day pack for a quick weekend in Old San Juan to a 5GB/30-day pack for a longer island stay - and your eSIM QR code with installation instructions arrives by email straight after purchase.
- Install the eSIM profile. While still on Wi-Fi, open your phone's mobile network settings, choose "Add eSIM" or "Add Cellular Plan," and scan the QR code, or tap the install link if you're viewing it on the same device. The profile downloads in under a minute.
- Land and let it connect. Once you touch down in Puerto Rico, turn on data roaming for the new eSIM line and set it as your data line. Your phone picks up a Claro, Liberty, or T-Mobile signal as you leave the terminal, so you can order a rideshare or pull up directions without hunting for airport Wi-Fi.
Coverage in Puerto Rico
Puerto Rico's mobile network is split between three main operators: Claro, with broad territorial reach and 5G extending outward from San Juan; Liberty, which took over AT&T's former island operations and is known for consistent voice and data quality; and T-Mobile, which also runs a competitive 5G network in built-up areas. Between them, coverage is close to nationwide across the populated coastal belt and the main urban centres.
5G is live in San Juan and the other major cities, with all three operators expanding their footprint outward from the metro area. As you move away from San Juan and the coastal corridor, phones will often fall back to a solid 4G connection rather than 5G - still enough for maps, messaging, and video calls in most towns.
The gaps show up inland. The mountainous interior and highlands, including parts of the Sierra de Luquillo, can see signal drop to 3G or disappear in pockets, and El Yunque National Forest - despite being one of the island's best-known day trips - has patches where elevation and tree cover cause signal to fluctuate. If you're hiking there, don't rely on data for navigation the whole way. Offshore, Vieques and Culebra have their own quirks: terrain on both islands means coverage can be inconsistent, so don't assume a strong signal at Flamenco Beach on Culebra just because you had one back on the main island.
In short, expect reliable data in San Juan, Old San Juan, and along the main highways connecting coastal towns, and treat anything in the mountains, deep inside El Yunque, or on the smaller islands as a bonus rather than a guarantee.
How much data do you need in Puerto Rico?
Data use in Puerto Rico varies a lot depending on whether you're mostly in San Juan or splitting your trip with the mountains and outer islands. Use this as a rough guide when picking a plan size.
| Usage level | Typical daily use | Suggested plan |
|---|---|---|
| Light | Maps, messaging, and occasional browsing - around 300MB a day | 1GB / 7 days - ideal for a long weekend around San Juan |
| Moderate | Social media, music, and regular photo uploads - around 750MB a day | 3GB / 15 days - suited to a week or two exploring the coast and El Yunque |
| Heavy | Video calls, streaming, and navigation-heavy days - 1.5GB or more a day | 5GB / 30 days - for a longer stay split between San Juan, Vieques, and Culebra |
eSIM vs. international roaming vs. a local SIM
Whether an eSIM makes sense depends on the phone plan you're already carrying into Puerto Rico.
| eSIM | International roaming | Local SIM card | |
|---|---|---|---|
| Setup | Install the profile before you fly; it's active as soon as you land | Works automatically on arrival, no setup needed | Requires a shop visit and photo ID under Puerto Rico's prepaid registration law |
| Cost for non-US visitors | A single upfront plan from £2.42, no surprise charges | Home carriers can charge heavily per megabyte, plus day-pass add-ons | Reasonable local rates, but only worthwhile if you're staying long enough to justify the paperwork |
| Cost for US phone plans | Usually unnecessary - most US postpaid plans treat Puerto Rico as domestic | None - Puerto Rico is billed as domestic by AT&T, Verizon, and T-Mobile home plans | Unnecessary for US postpaid customers |
| Registration hassle | None beyond your device details for activation | None | The seller must record your name, address, phone number, and device details at the point of sale |
Practical connectivity tips for Puerto Rico
Because Puerto Rico is a US territory, the first thing to check before you fly is whether your own phone plan already treats it as domestic. If you're on a US postpaid plan with AT&T, Verizon, or T-Mobile, you may not need an eSIM at all. An eSIM makes the biggest difference for non-US visitors, who would otherwise face home-carrier international roaming charges for every megabyte used on the island.
Install your eSIM and confirm it's active before you land, so you're not relying on airport Wi-Fi to get a rideshare or directions out of San Juan. Download an offline map for El Yunque and for day trips to Vieques or Culebra, since signal in the rainforest and on the smaller islands can fade in and out. Along the coast and in the main towns, data is generally reliable enough for calls, streaming, and uploading photos without a second thought. If you're buying a physical local SIM instead, bring photo ID with you, since Puerto Rico's prepaid registration rules mean a shop can't activate a line without it.

Frequently asked questions about eSIMs for Puerto Rico
If I already have a US phone plan, do I still need an eSIM in Puerto Rico?
Most US postpaid plans from AT&T, Verizon, and T-Mobile treat Puerto Rico as domestic, so you won't pay roaming charges there. An eSIM is mainly useful if you're on a prepaid plan, a non-US carrier, or you just want a dedicated data line for the trip.
What is Puerto Rico's prepaid SIM registration law?
Puerto Rico law (Title 27, Section 535) requires anyone buying a prepaid SIM to register with the seller, providing your name, address, phone number, and device details. Bring photo ID if you plan to buy a physical local SIM rather than using an eSIM.
Does eSIM coverage reach El Yunque National Forest?
Partly. Towns around the edge of El Yunque generally have a usable signal, but the rainforest's elevation and tree cover cause coverage to fluctuate as you climb higher, so treat data as unreliable once you're deep inside the park.
Will my eSIM work on Vieques and Culebra?
Yes, but coverage on both islands is less consistent than on the Puerto Rico mainland because of their terrain, so expect signal to vary around Flamenco Beach on Culebra and in more remote parts of Vieques.
Which network covers San Juan best?
Claro, Liberty, and T-Mobile all run solid networks in San Juan and Old San Juan, with 5G live across the metro area, so day-to-day differences usually come down to your particular phone rather than a coverage gap.
How much data do I actually need for a week in Puerto Rico?
It depends on how you use your phone: light use such as maps and messaging fits comfortably into a 1GB/7-day plan, while regular photo uploads and streaming point you toward a 3GB/15-day plan instead.
Is it cheaper to use an eSIM than international roaming in Puerto Rico?
For non-US visitors, generally yes - international roaming on Puerto Rico can be billed at steep per-megabyte or day-pass rates by home carriers, while a Puerto Rico eSIM plan is a single fixed cost from £2.42.
Do I need my passport to buy a SIM card in Puerto Rico?
If you're buying a physical prepaid SIM, yes - Puerto Rico's registration law requires the seller to record identifying details at the point of sale, which typically means showing a passport or other photo ID.
What number do I dial for emergencies in Puerto Rico?
Dial 911, the same emergency number used across the United States, since Puerto Rico is a US territory.
Will my eSIM support 5G in Puerto Rico?
5G is live in San Juan and other major cities on all three main networks, so a 5G-capable eSIM plan will connect at 5G speeds in urban areas, falling back to 4G once you head into rural or mountainous parts of the island.
