If you've already decided that you're going to bring data and the only thing left is to choose the package size, this guide is about just that: how many GB you need for Puerto Rico and not one more. I'm not going to repeat the comparison of connection options here, because you already have that in another article. Here we're getting to the number, with real consumption tables, a recommendation per travel profile, and the particularities of the island that make the calculation different from other destinations. And yes, it includes an important warning about data plans if you're traveling from Spain.
The quick answer: how many GB for Puerto Rico
For a 7-10 day trip to Puerto Rico, most people will be fine with 5 GB. If you only use maps and WhatsApp, 3 GB will suffice; if you upload videos daily or make long video calls from the beach, go up to 10 GB.
That's the number, and I'm not going to hide behind a "it depends." Puerto Rico is a medium-low consumption destination compared to other long trips, and there are three specific reasons. First: Wi-Fi works reasonably well in hotels and accommodations in San Juan, Condado, Isla Verde, and Rincón, so you can do heavy downloads there. Second: a good part of the trip is spent in places where there is no coverage to use data at all, such as the interior of El Yunque or the beaches of eastern Vieques. And third, the one most people overlook: Spanish is spoken there. You don't need the translator with the camera on all day, which is what drives up consumption in Japan, Thailand, or Morocco.
A typical 7 to 10-day trip with a base in San Juan, two or three excursions, and a getaway to the islands will use between 2.5 and 4 GB in reality. Buying 5 GB gives you a margin without wasting money. If you want to understand the general logic before deciding, you have the complete framework in the guide on how much data I need for travel.
Why Puerto Rico changes the calculation (and the Spanish plan warning)
Here's the most important particularity and the one that causes the most trouble: Puerto Rico is U.S. territory. This has a very specific practical consequence depending on where you're coming from.
If you're traveling from the United States, your regular mobile plan probably already includes Puerto Rico as domestic use, with no extra cost. Major U.S. carriers treat it as another part of the country. But if you're traveling from Spain, and this is what I want you to take away from this section, your tariff does not cover Puerto Rico the same way it covers the European Union: there, you leave the European space and enter international billing, which is expensive and eats up your balance in a short time. Checking this before you fly will save you a shock on your bill.
There's a second detail that confuses many people when buying data: a "Caribbean" package doesn't always include Puerto Rico, because it's technically U.S. territory, while many U.S. packages do cover it. Before paying, check the plan's coverage and look for "Puerto Rico" in the list; don't rely on the region.
The good news: since it's U.S. territory, the network is the U.S. network. There is solid 4G and 5G on the main island, with no website blocks or need for a VPN, so there's no extra consumption there. If you want details on how to connect, you can find them in internet in Puerto Rico.
How much each thing you'll do there actually consumes
Before choosing a package, it's good to have an idea of the orders of magnitude, because almost everyone makes the same mistake: they think maps consume a lot (they consume very little) and that social media consumes little (they eat up the package by themselves). These are the approximate figures I handle, in MB per hour of active use:
| Activity | Approximate Consumption | On a normal day |
|---|---|---|
| Google Maps navigation | 3-5 MB/hour | 15-30 MB |
| WhatsApp: text, photos, and audio | — | 5-15 MB |
| WhatsApp voice call | 30-60 MB/hour | 20-60 MB |
| Video call (WhatsApp, FaceTime) | 250-500 MB/hour | Depends on you |
| Instagram or TikTok, scrolling through videos | 600-1,000 MB/hour | 300-600 MB |
| Uploading a phone photo | 3-5 MB per photo | 60-150 MB (20-30 photos) |
| Uploading a short video (30s) | 30-60 MB | 100-300 MB |
| Music streaming | 40-150 MB/hour | 100-300 MB |
| Video streaming (normal quality) | 500-1,000 MB/hour | Avoid it with data |
| Email and web browsing | 20-60 MB/hour | 50-150 MB |
Notice the jump: a single hour of social media videos uses more data than an entire week of Google Maps navigation. If you have GBs left over when you return, it's almost always because you limited your scrolling. If you run out, it's almost always the opposite. You can find the expanded breakdown in the mobile data usage statistics by activity.
How many GB according to your profile and the days you're staying
This is the table that really matters. Find the row that matches you, cross-reference it with your travel days, and you'll have your number. It's designed for one phone, except for the family row, which assumes multiple devices sharing the same package.
| Travel Profile | 5 days | 10 days | 15 days | 30 days |
|---|---|---|---|---|
| Tourist using maps and WhatsApp | 1-2 GB | 3 GB | 5 GB | 10 GB |
| Photos and social media | 3 GB | 5 GB | 8 GB | 15 GB |
| Digital nomad / remote work | 10 GB | 20 GB | 30 GB | 50 GB or unlimited |
| Family sharing (2 adults + 2 children) | 5 GB | 10 GB | 15 GB | 25 GB |
Since the typical trip to Puerto Rico lasts between 7 and 10 days, the column you'll be looking at is the middle one. In other words: 3 GB if you only open your phone to navigate and check in at home, 5 GB if you post daily, and 10 GB or more if you work from there.
A couple of honest nuances about this table. If your accommodation has good Wi-Fi and you plan to use it at night, you can easily go down a step. If you're going to rent a car and travel all over the island, you don't need to go up: navigation uses much less data than it seems. And if you make long video calls with family, go up a step without thinking, because that's the only activity on this list capable of messing up your forecast in two afternoons. The package you buy should sound like the number in your cell, not the largest one in the store.
San Juan and Old San Juan: maps and photos all day long
Old San Juan is best explored on foot with your phone in hand almost all the time, and that combination is what most people fear. Don't worry: it can be covered in a few hours, the streets are a grid, and navigation barely uses any data. A full day of walking around the old town, El Morro, San Cristóbal, Fortaleza Street, and La Princesa promenade will only use about 15-30 MB for maps. Nothing.
What does use data there is photos. Old San Juan is one of the most photogenic places in the Caribbean, and you'll end up with two hundred photos before you know it. As long as they stay on your phone, zero data. The problem arises when your phone decides to upload them to the cloud automatically as soon as it sees a connection: then you could easily use 500 MB or 1 GB in an afternoon. In the tips section, I'll explain how to prevent that.
| Typical day in Puerto Rico | Estimated consumption |
|---|---|
| Day on foot in Old San Juan (maps, WhatsApp, 30 photos, some social media) | 300-500 MB |
| Road trip day around the island (4 hours of navigation, music, messages) | 200-350 MB |
| Hiking day in El Yunque | 50-100 MB |
| Beach day in Culebra or Vieques | 100-200 MB |
| Remote work day (2 hours of video calls, email, browsing) | 1.2-2 GB |
Multiply your days by the row that applies to you and you'll see that the number comes out without any fancy formulas. A 10-day trip mixing these typical days will be around 3 GB.
El Yunque, Culebra, and Vieques: where your phone rests
Here's the good news about Puerto Rico: a significant part of the trip takes place in areas where you won't use data because there's no coverage to use. In El Yunque, the signal holds up on the entrance road and in parking lots, but as soon as you go into the interior trails or down to the waterfalls, your phone will go blank. In Culebra and Vieques, there's decent 4G in the towns (Dewey, Isabel Segunda, Esperanza) and it becomes intermittent on more secluded beaches and during the ferry crossing.
| Area | Typical Coverage | What it means for your data |
|---|---|---|
| San Juan, Condado, Isla Verde | Solid 4G/5G | Normal consumption, abundant Wi-Fi |
| Highways and cities (Ponce, Arecibo, Mayagüez) | Good 4G/5G | Seamless navigation |
| El Yunque (trails and interior) | Spotty or none | Bring downloaded map; almost zero data usage |
| Central Mountain Range and mountain roads | Dead zones | Download your route before going |
| Ceiba-Culebra/Vieques ferry | Intermittent | No video during the crossing |
| Culebra and Vieques (beaches) | Weak, poor accommodation Wi-Fi | Download music and podcasts before going |
In Culebra and Vieques, don't take Wi-Fi for granted at your accommodation. That's where most people end up relying on mobile data just when the signal is worst, so download everything you want to listen to or watch beforehand.
If you're going to the smaller islands by small plane or ferry, make sure you have your ticket and reservation saved on your phone without relying on the internet: screenshot or downloaded PDF. To choose a plan size with this in mind, check the eSIM options for Puerto Rico.
Rental car: the whole island with the GPS on
Puerto Rico is best explored by car. It's normal and recommended: the main island is about 170 km from east to west, and in a day you can reach Ponce, Cabo Rojo, or the bioluminescent bay of La Parguera. Many people assume that having the navigator on five or six hours a day will eat up their data plan. It's not true: Google Maps navigation uses around 3-5 MB per hour, so an entire week on the road is about 150 MB in total. Less than ten minutes of videos on social media.
What you should watch out for in the car is what's playing in the background. Music streaming during journeys uses between 40 and 150 MB per hour depending on the quality, and that can add up: four hours of daily driving with high-quality music is half a gigabyte a day. The solution is travel basics: download playlists via Wi-Fi at your accommodation and put them in offline mode.
A coverage warning: if you go up to the Ruta Panorámica or cross the Central Mountain Range, there are sections without signal. Download the map of the entire island before you leave, and the navigator will continue to work even if your phone loses signal. It takes up space on your phone, not data. And if the rental car offers paid navigation for a few dollars a day, skip it: what your phone uses doesn't justify the cost.
Video calls from the beach and photo backups: the two thieves
If your forecast goes awry in Puerto Rico, it's most likely due to one of these two things. I know them well because they are the two that appear most often when someone tells me "I've run out of data and I don't know why."
First, video calls. Showing the family Flamenco beach live is irresistible, and a video call consumes between 250 and 500 MB per hour. Half an hour a day for ten days is 1.5-2.5 GB: half of a 5 GB package due to a single habit. I'm not telling you not to make them, I'm telling you to count them when choosing the size. And if you can, make them from the accommodation's Wi-Fi at night, which also looks better.
Second, automatic photo backup. With all the photos taken on this trip, leaving automatic upload to Google Photos or iCloud active with mobile data is the fastest way to run out. A day of photos and some videos can easily be 1 GB. Go into the settings and set backups to be Wi-Fi only before you leave home.
There's a third, minor but real thief: app updates. Disable automatic updates over data in the app store, and you'll prevent your phone from downloading half a gigabyte of updates while you're having breakfast in Ponce.
Calculate your real consumption before you fly
All of the above are averages, and you are not an average. The honest way to get the number right is to look at your own consumption, which you already have measured in your pocket. It's a minute of work and worth more than any table.
- On Android: Settings > Network & internet > SIM or Data usage. You'll see the current month's GB and the breakdown by app.
- On iPhone: Settings > Mobile Data. Scroll down to the app list and look at the period indicated at the very bottom (it's a good idea to reset the statistics for a month to get clean data).
With that monthly number, divide by 30 to get your daily consumption at home. Then adjust it for the trip with two corrections: add 30-50% because you'll use more maps, search for more things, and share more while traveling; and subtract what you do over Wi-Fi at your accommodation, which in Puerto Rico is quite a bit. Multiply by the number of days and round up to the next package size.
Real example of how the calculation works: if you use 6 GB per month in Spain, that's 200 MB per day; with the travel bonus, about 300 MB per day; for ten days, 3 GB. There you have the same number the table gave you, but calculated with your data. When both methods coincide, you can buy with confidence. If they don't coincide, trust yours: the table is an average, your settings are the truth.
How to stretch your GBs and what happens if you run out
With four adjustments made before leaving home, the same trip costs you half the data. These are the ones that really move the needle in Puerto Rico:
- Download the island map in Google Maps via Wi-Fi. It covers El Yunque, the Cordillera, and roads without signal.
- Backups only via Wi-Fi, for both photos and your phone's cloud.
- Data saver mode activated in the system and within Instagram, TikTok, and YouTube.
- Disable automatic video playback on social media and WhatsApp; and disable automatic download of photos and videos from groups.
- Music and podcasts downloaded before getting in the car or on the ferry.
You can find more ideas in the guide on how to save data while traveling.
What if you run out of data? It's not a big deal, and that's why I always recommend getting less rather than more. When your plan runs out, you simply no longer have data: you can recharge in a couple of minutes using Wi-Fi at a hotel, a cafe, or the airport, and continue on. On the other hand, if you buy 20 GB and only use 4 GB, that money is gone. Buying too little can be fixed, buying too much cannot. Start with the plan your table box suggests and recharge mid-trip if needed, which is exactly what most people do.
Frequently Asked Questions
How many GB do I need for 7 days in Puerto Rico?
3 GB is enough for a week if you use maps, WhatsApp, and social media in moderation. If you post daily stories or make long video calls, get 5 GB. Only go beyond that if you plan to work remotely from there.
Does my Spanish plan work in Puerto Rico?
Not like in Europe. Puerto Rico is a U.S. territory and outside the European zone, so it's billed as an international destination and can be expensive. Check your carrier's terms before flying, as many don't even offer a plan for this region.
Does a U.S. data plan cover Puerto Rico?
Usually yes, because the networks are the same and U.S. carriers treat it as domestic use. Even so, make sure "Puerto Rico" appears on the coverage list: there are regional Caribbean packages that, paradoxically, exclude it. If all this sounds confusing, start with what an eSIM is.
Is there coverage in El Yunque, Culebra, and Vieques?
patchy. In El Yunque, the signal disappears on inland trails; in Culebra and Vieques, there's 4G in the towns but it's weak on secluded beaches and the ferry. Download maps and tickets before you go and don't rely on Wi-Fi at accommodations on the smaller islands.
How much data does the browser use if I rent a car?
Very little: 3-5 MB per hour. A whole week driving around the island is about 150 MB. What does use data in the car is music streaming, between 40 and 150 MB per hour, so download it via Wi-Fi before leaving.
What if I run out of data halfway through my trip?
Just recharge. You'll lose mobile connection until you do, but you can extend your plan in a couple of minutes from any Wi-Fi. That's preferable to buying twice what you need and wasting it.
Do I need a VPN or translator in Puerto Rico?
Neither. There are no blocked websites or censored services, so you won't use extra data on a VPN. And Spanish is an official language, so you save on a camera translator, which significantly increases consumption in other destinations.
How many GB for two people or a family?
For a 10-day family trip, estimate about 10 GB shared. If each person has their own plan, apply the table per profile to each phone: typically, one uses maps and another uses social media, and they don't consume anywhere near the same amount.
Conclusion
Puerto Rico is a cheap data destination, and there's no need to overcomplicate things. For a typical 7- to 10-day trip, 5 GB is a sensible purchase: it covers maps, messaging, photos, and normal social media use with plenty of margin. If you barely look at your phone, 3 GB is enough, and I prefer to tell you that even though we sell larger plans. If you work from there or are constantly on video calls, go for 10 GB or more and rest easy.
Do the two checks I mentioned before buying: look at your real consumption in your phone settings and confirm that the plan you choose explicitly includes Puerto Rico, not just "Caribbean" or "America." With that, there will be no surprises.
Once you're clear, you have the eSIM for Puerto Rico ready to activate before leaving home: you land in San Juan with data from the first minute, without looking for a store or struggling with airport Wi-Fi. And if you run out of data halfway through your trip, you recharge from your phone and continue.
