eSIM Puerto Rico
Best eSIM for Puerto Rico: 8 Providers Ranked
Apr
Fact-checked by Eric Stevens
Puerto Rico catches visitors off guard.
It’s a US territory, but the eSIM situation is not what you’d expect.
Some providers sell Puerto Rico as a separate destination. Others bundle it under their USA plan, meaning your American eSIM already works the moment you land in San Juan. The difference can save you money or leave you buying a plan you didn’t need.
Below we break down the 8 best eSIMs for Puerto Rico, what each one costs, which networks they connect to, and how the US territory angle changes your options so you can pick the right plan before you board.

eSIM4: widest plan range for Puerto Rico
| Rating: | |
| Supported networks: | 4G/5G (T-Mobile, AT&T) |
| Countries covered: | 190+ |
| Starting price: | $3.98 / 1 GB / 7 days |
| Calls & texts: | Available via the Yabb app (paid add-on) |
eSIM4 is our recommended provider for Puerto Rico because it offers the most competitive pricing with a dedicated Puerto Rico plan. At $3.98 for 1 GB, it undercuts almost every competitor on this list. Plans range from lightweight 1 GB packages for a weekend getaway to unlimited 30-day options for extended stays, and you can install everything before you fly.
Network Coverage
Puerto Rico benefits from full US carrier infrastructure. eSIM4 connects through T-Mobile and AT&T, which together cover the vast majority of the island, including San Juan, Ponce, Mayaguez, and the coastal towns. Coverage thins out in mountainous interior areas and deep inside El Yunque National Forest, but the main roads and tourist corridors have strong 4G signal.
Data Plans
eSIM4 offers twelve Puerto Rico plans, from 1 GB / 7 days up to Unlimited / 30 days. That range is the widest of any provider on this list for Puerto Rico specifically. The mid-tier options (3 GB and 5 GB at 30 days) offer strong value for a typical week-long trip. Heavy users can jump straight to unlimited plans starting at $18.98 for 3 days.
Activation Process
Scan the QR code in your phone’s settings app. The whole process takes under five minutes. Set up your new eSIM before you fly and activate it when you land at Luis Munoz Marin International Airport (SJU) for instant connectivity on arrival. Data speeds across San Juan average 25-50 Mbps on 4G, with 5G available in parts of the metro area.

Pros
- Widest plan range: 12 plans from 1 GB to unlimited, covering every trip length
- Dedicated Puerto Rico plan: no need to buy a broader USA eSIM
- Pre-travel setup: install before you fly, activate on arrival at SJU
- 190+ countries covered: one account works beyond Puerto Rico for onward travel
Cons
- Calls require Yabb app: calls and texts are available but through the companion Yabb app, not the native dialler
- Unlimited 30-day plan is premium: $97.98 is steep for extended heavy use
GigSky: unlimited USA plans that cover Puerto Rico
| Rating: | |
| Supported networks: | 4G/5G (T-Mobile, AT&T) |
| Countries covered: | 180+ |
| Starting price: | $3.99 / 1 GB / 7 days (USA plan) |
GigSky covers Puerto Rico through its USA plans. That means one eSIM works in both the mainland US and Puerto Rico with no extra purchase. If your trip includes a stopover in Miami or New York before heading to San Juan, GigSky’s approach saves you from juggling two separate eSIMs. The unlimited plans are the standout here, starting at just $3.99 for a single day.
Network Coverage
GigSky uses US carrier networks (T-Mobile and AT&T) in Puerto Rico, delivering identical coverage to what you’d get on the mainland. Strong 4G/5G across San Juan, Ponce, and Fajardo. Interior mountain roads and El Yunque trails will have spotty signal regardless of provider.
Data Plans
GigSky offers both fixed data and unlimited plans. The fixed plans (1 GB to 5 GB) are competitively priced with a 20% discount currently applied. The unlimited plans throttle after 2.5 GB per day to slower speeds. For casual browsing, maps, and messaging that daily cap is fine. Video calls and streaming will feel the throttle in the afternoon if you’re a heavy user.
Activation Process
Standard QR code activation. The app experience is functional but less polished than Airalo or eSIM4. Setup is straightforward for anyone who has installed an eSIM before. First-time users may want a provider with a more guided walkthrough.
Price
| Data | Duration | Price |
|---|---|---|
| 1 GB | 7 days | $3.99 |
| 3 GB | 15 days | $9.59 |
| 5 GB | 30 days | $15.99 |
| Unlimited* | 1 day | $3.99 |
| Unlimited* | 3 days | $11.99 |
| Unlimited* | 7 days | $23.19 |
| Unlimited* | 14 days | $35.19 |
| Unlimited* | 30 days | $59.99 |
*Unlimited plans throttle after 2.5 GB/day. Prices reflect current 20% discount.
Pros
- USA + Puerto Rico on one plan: no separate purchase needed if combining destinations
- Unlimited plans available: rare for Puerto Rico coverage, starting at $3.99/day
- Competitive fixed plans: 20% discount brings prices in line with the lowest on this list
Cons
- Unlimited throttles after 2.5 GB/day: speed drops once you hit the daily cap, resets next day
- Less polished app: setup flow is not as smooth as Airalo or eSIM4
- Slower support: response times can lag compared to competitors
Airalo: most trusted name with USA plans covering Puerto Rico
| Rating: | |
| Supported networks: | 4G/5G (T-Mobile, AT&T) |
| Countries covered: | 200+ |
| Starting price: | $4.00 / 1 GB / 3 days (USA plan) |
Airalo is the largest eSIM marketplace in the world, and its USA plans cover Puerto Rico automatically. There is no separate Puerto Rico listing on Airalo; you purchase a USA eSIM and it works on the island. For travellers who already know Airalo from previous trips, the familiar app and setup process remove any guesswork.
Network Coverage
Airalo connects via US carrier networks in Puerto Rico, delivering strong 4G/5G coverage across the San Juan metro area, Condado, Isla Verde, and the main coastal highways. Network performance is identical to mainland USA coverage. The same dead zones apply: El Yunque hiking trails and remote interior mountain roads.
Data Plans
Airalo’s USA plan range is extensive: twelve options from 1 GB / 3 days to 50 GB / 30 days. The 3-day and 7-day validity windows are useful for short Puerto Rico trips where a 30-day plan would be wasteful. The 50 GB / 30-day plan at $42 is strong value for heavy users. No unlimited plans are available.
Activation Process
Airalo’s app is consistently rated one of the best in the category. Clear setup flow, step-by-step QR code guidance, and a large user community for troubleshooting. Install before departure and activate on arrival at SJU. Particularly good for first-time eSIM users who want a polished experience.
Price
| Data | Duration | Price |
|---|---|---|
| 1 GB | 3 days | $4.00 |
| 3 GB | 7 days | $9.00 |
| 5 GB | 7 days | $13.00 |
| 10 GB | 15 days | $22.50 |
| 20 GB | 30 days | $37.00 |
| 50 GB | 30 days | $42.00 |
All plans are USA eSIMs that cover Puerto Rico automatically.
Pros
- Most trusted eSIM brand: largest marketplace globally with extensive user reviews
- Polished app: consistently one of the best eSIM apps available
- Wide plan variety: 3, 7, 15, and 30-day validity options across multiple data tiers
Cons
- No dedicated Puerto Rico plan: must buy the USA eSIM, which may confuse some travellers
- No unlimited: capped plans only
Nomad: strong mid-range value with large data tiers
| Rating: | |
| Supported networks: | 4G/5G (T-Mobile, AT&T) |
| Countries covered: | 200+ |
| Starting price: | $4.50 / 1 GB / 7 days |
Nomad offers a dedicated Puerto Rico eSIM with plans that scale well for longer stays. The 50 GB / 30-day plan at $49 is the best value on this list for heavy data users who prefer a fixed allowance over unlimited throttled plans. Nomad’s app is clean and the activation process is straightforward.
Network Coverage
Nomad connects through T-Mobile and AT&T in Puerto Rico. Coverage across the San Juan metro, Ponce, and major coastal towns is strong. 5G is available in parts of the San Juan area where carrier infrastructure supports it. Interior mountain coverage is limited, consistent with all providers on this list.
Data Plans
Six plans from 1 GB / 7 days to 50 GB / 30 days. The 5 GB / 30-day plan at $15 is competitive with eSIM4. The jump to 50 GB at $49 is where Nomad shines; that tier is priced lower than Airalo’s 50 GB equivalent. No unlimited plans, but the large data tiers reduce the need for one.
Activation Process
Clean QR code activation through the Nomad app. Install before departure and activate on arrival. The app is well designed and plan management is clear. No complications specific to Puerto Rico.
Price
| Data | Duration | Price |
|---|---|---|
| 1 GB | 7 days | $4.50 |
| 3 GB | 30 days | $11.00 |
| 5 GB | 30 days | $15.00 |
| 10 GB | 30 days | $25.00 |
| 20 GB | 30 days | $35.00 |
| 50 GB | 30 days | $49.00 |
Pros
- 50 GB at $49: best value for heavy data users who want a fixed plan
- Dedicated Puerto Rico plan: no confusion about USA plan coverage
- Clean app: straightforward setup and management
Cons
- No unlimited option: capped plans only for Puerto Rico
- Entry plan slightly pricier: $4.50 for 1 GB vs. eSIM4’s $3.98
Saily: built-in privacy tools from the NordVPN team
| Rating: | |
| Supported networks: | 4G/5G (T-Mobile, AT&T) |
| Countries covered: | 150+ |
| Starting price: | $3.99 / 1 GB / 7 days |
Saily, made by the team behind NordVPN, includes built-in privacy tools: ad blocker, virtual location, and web protection. Puerto Rico’s tourist areas (Condado, Isla Verde, Old San Juan) are full of open hotel and cafe Wi-Fi networks. Having security baked into your eSIM app rather than running a separate VPN is a genuine convenience.
Network Coverage
Saily connects through T-Mobile and AT&T in Puerto Rico, delivering solid 4G/5G performance across the San Juan metro area, Rincon, and Ponce. Coverage matches other providers on this list. El Yunque rainforest trails and remote mountain areas have the same signal limitations regardless of provider.
Data Plans
Five plans from 1 GB / 7 days to 20 GB / 30 days. Plan variety is more limited than Airalo or Nomad, but the core tiers cover most trip lengths. The 1 GB entry price at $3.99 matches GigSky as the joint-lowest on this list. No unlimited plans available.
Activation Process
Clean QR code activation through the Saily app, consistent with NordVPN’s standard of polished product design. The app also manages the built-in privacy features from the same interface, so there is no need for a separate VPN app during your trip.
Price
| Data | Duration | Price |
|---|---|---|
| 1 GB | 7 days | $3.99 |
| 3 GB | 30 days | $10.99 |
| 5 GB | 30 days | $16.99 |
| 10 GB | 30 days | $24.99 |
| 20 GB | 30 days | $36.99 |
Pros
- Built-in privacy tools: ad blocker, virtual location, and web protection included
- Security-focused: backed by the NordVPN team with a strong privacy track record
- Low entry price: $3.99 for 1 GB ties for the lowest on this list
Cons
- Fewer plan options: no unlimited and tops out at 20 GB
- 150 countries: fewer destinations covered than Airalo or Nomad
Jetpac: WhatsApp and Maps keep working after data runs out
| Rating: | |
| Supported networks: | 4G/5G (multi-network) |
| Countries covered: | 200+ |
| Starting price: | $7.00 / 1 GB / 4 days |
Jetpac’s standout feature is something no other provider on this list offers: WhatsApp, Google Maps, Uber, and Grab continue working even after your data allowance runs out. In Puerto Rico, where Uber and Lyft are the primary transport option in San Juan and Google Maps is essential for navigating Old San Juan’s maze of one-way streets, that safety net has real value.
Network Coverage
Jetpac uses multi-network support, automatically connecting to the strongest available carrier. In Puerto Rico that means T-Mobile or AT&T depending on location. 5G is explicitly supported in metro San Juan. Coverage quality is on par with other providers across the island’s main tourist areas.
Data Plans
Seven plans from 1 GB / 4 days ($7) up to 30 GB / 30 days ($69.99). The 5 GB and 10 GB tiers are where Jetpac becomes competitive. Jetpac also offers voice calling packs to 50+ countries starting at $1.99 for 5 minutes, useful for calling restaurants, hotels, or local businesses directly.
Price
| Data | Duration | Price |
|---|---|---|
| 1 GB | 4 days | $7.00 |
| 3 GB | 7 days | $21.00 |
| 5 GB | 30 days | $21.00 |
| 10 GB | 30 days | $36.00 |
| 15 GB | 30 days | $49.99 |
| 20 GB | 30 days | $100.00 |
| 30 GB | 30 days | $69.99 |
Pros
- Essential apps after data runs out: WhatsApp, Google Maps, Uber keep working at zero data
- Voice calls available: call landlines and non-WhatsApp numbers in 50+ countries
- 5G supported: faster speeds in San Juan where available
Cons
- Expensive entry point: $7 for 1 GB is the highest starting price on this list
- 20 GB plan pricing oddity: costs more than the 30 GB plan
aloSIM: unlimited plans with a phone number included
| Rating: | |
| Supported networks: | 4G/5G (T-Mobile, AT&T) |
| Countries covered: | 200+ |
| Starting price: | $4.50 / 1 GB / 7 days |
aloSIM stands out for two reasons: it includes a phone number with every plan, and it offers unlimited data options for Puerto Rico. Most travel eSIMs are data-only, meaning you rely on WhatsApp or VoIP for communication. With aloSIM, you get a number you can share with hotels, tour operators, or car rental agencies who may want to call you directly.
Network Coverage
aloSIM connects through T-Mobile and AT&T in Puerto Rico. Coverage across San Juan, Ponce, Fajardo, and the main tourist corridors is strong. Data is fully unthrottled on fixed plans with no speed caps at any point.
Data Plans
Twelve plans from 1 GB / 7 days ($4.50) to Unlimited / 30 days ($99). The fixed data plans are competitively priced. The unlimited options mirror eSIM4’s range but at slightly higher price points. No ID or documentation required to purchase; installation claims 90 seconds.
Price
| Data | Duration | Price |
|---|---|---|
| 1 GB | 7 days | $4.50 |
| 2 GB | 15 days | $8.00 |
| 3 GB | 30 days | $11.00 |
| 5 GB | 30 days | $17.00 |
| 10 GB | 30 days | $25.00 |
| 20 GB | 30 days | $39.00 |
| Unlimited | 3 days | $20.50 |
| Unlimited | 5 days | $29.50 |
| Unlimited | 7 days | $36.50 |
| Unlimited | 10 days | $38.00 |
| Unlimited | 15 days | $49.00 |
| Unlimited | 30 days | $99.00 |
Pros
- Phone number included: rare for a travel eSIM; useful for hotel bookings and local calls
- Unlimited plans available: full range from 3 to 30 days
- Fully unthrottled: no speed caps on fixed data plans
Cons
- Slightly pricier than eSIM4: comparable plans cost $0.50-$2 more
- Unlimited 30-day at $99: on par with eSIM4 but no savings discount shown
Roamless: pay-as-you-go with no expiry
| Rating: | |
| Supported networks: | 4G/5G (T-Mobile, AT&T) |
| Countries covered: | 200+ |
| Starting price: | $2.45/GB (pay-as-you-go) |
Roamless takes a completely different approach: no fixed plans, no validity windows, no expiry dates. You load credit, use data at $2.45 per GB in Puerto Rico, and your balance carries forward to your next trip anywhere in the world. For travellers who hate overpaying for data they will not use, or whose trip length is unpredictable, this model is genuinely liberating.
Network Coverage
Roamless uses T-Mobile and AT&T in Puerto Rico with no speed throttling. Coverage across San Juan, the island’s coastal towns, and the main highways is strong. The pay-as-you-go model means you only pay for what you actually consume, so weak-signal areas like El Yunque do not cost you anything.
Data Plans
There are no fixed plans. You buy credit and use it at $2.45 per GB. This makes Roamless the lowest per-GB rate on this list by a significant margin. For context, 5 GB on Roamless costs $12.25 vs. $15.98 on eSIM4 or $16.99 on Saily. The catch: you need to estimate your usage upfront when loading credit. Roamless also offers calls, texts, and virtual numbers through the same app.
Price
| Data | Duration | Price |
|---|---|---|
| 1 GB | No expiry | $2.45 |
| 5 GB | No expiry | $12.25 |
| 10 GB | No expiry | $24.50 |
| 20 GB | No expiry | $49.00 |
Prices calculated at $2.45/GB. Actual purchase is credit-based; use as much or as little as needed.
Pros
- Lowest per-GB cost: $2.45/GB significantly undercuts all fixed-plan providers
- No expiry: credits carry forward to future trips worldwide
- No waste: only pay for the data you actually use
Cons
- No fixed plans: requires estimating your usage and loading credit upfront
- No unlimited option: pay-as-you-go only; heavy users may prefer a flat-rate plan

What you should know before getting a Puerto Rico eSIM
Puerto Rico is a US territory with full US carrier coverage
T-Mobile, AT&T, and Claro Puerto Rico provide strong 4G/5G coverage across the island. This means most eSIM providers route through the same carriers you would use on the US mainland. Coverage in San Juan, Ponce, Mayaguez, and along the coastal highways is excellent. Interior mountain areas and remote southern coast towns have weaker signal.
No passport needed for US citizens
Puerto Rico is a domestic destination for Americans. No customs, no immigration, no passport required. You fly in with a standard US ID. This also means your existing US phone plan may already work here without roaming charges. Check with your carrier before buying an eSIM, as you might not need one at all.
US Dollar is the currency; your cards and apps work everywhere
Puerto Rico uses the US Dollar. Your American credit cards, debit cards, Apple Pay, Google Pay, Venmo, and Cash App all work exactly as they do on the mainland. No currency exchange needed, no foreign transaction fees on US-issued cards. ATMs dispense USD.
El Yunque rainforest has weak-to-no signal on hiking trails
El Yunque is the only tropical rainforest in the US National Forest System and one of Puerto Rico’s top attractions. Cell coverage reaches the visitor centre and the main parking areas, but once you are on the trails (La Mina, Mt Britton, El Yunque Peak), signal drops to zero. Download the trail map offline before you enter.
Old San Juan has full 4G coverage; great for walking with Maps
The historic district of Old San Juan is compact, walkable, and fully covered by 4G. Google Maps works perfectly for navigating the narrow cobblestone streets, finding restaurants, and locating the forts (El Morro and San Cristobal). Having live data here is genuinely useful; the grid layout breaks down in the older sections and GPS navigation saves time.
Uber and Lyft both operate across metro San Juan
Both rideshare apps work in Puerto Rico. Uber and Lyft cover the San Juan metro area (Condado, Isla Verde, Old San Juan, Santurce, Hato Rey) and are the easiest way to get from SJU airport to your hotel. Rides to Old San Juan from the airport typically cost $15-$25. Both apps require an active data connection to request a ride.
Spanish is the primary language; English widely understood in tourist areas
Spanish is the dominant language in Puerto Rico. In tourist-facing areas (Old San Juan, Condado, Rincon, Fajardo) English is widely understood. Outside those zones, particularly in smaller towns and the mountain interior, Spanish is essential. Google Translate works over your eSIM data and can be a genuine help at local restaurants and markets.
Vieques and Culebra islands have limited coverage
The offshore islands of Vieques and Culebra (home to Flamenco Beach and the Bioluminescent Bay) have noticeably weaker cell coverage than the main island. Coverage exists in the main towns (Isabel Segunda on Vieques, Dewey on Culebra) but drops off quickly on beaches and rural roads. Download offline maps before taking the ferry from Fajardo.
How to activate a Puerto Rico eSIM
Activating your Puerto Rico eSIM is straightforward. Most modern smartphones support eSIM technology (iPhone XS and later, Samsung Galaxy S20+, Google Pixel 3+), so compatibility is rarely an issue if your device was made after 2018. There are no physical SIM cards to swap; the eSIM is a digital SIM card (embedded SIM) built directly into your device. We recommend setting it up before you fly so you arrive at SJU already online.
QR code activation (most common)
- Purchase your Puerto Rico eSIM plan on the provider’s website or app
- Receive your QR code by email (usually instant)
- On your phone: Settings → Cellular / Mobile Data → Add eSIM → Scan QR Code
- Set the eSIM as your data line; it may activate automatically when you land, or toggle it on manually
- Toggle it on when your flight lands in San Juan
App-based activation
- Download the provider’s eSIM app (eSIM4, Airalo, GigSky, etc.)
- Create an account and purchase a Puerto Rico plan
- Follow the in-app installation steps; these walk you through the phone settings
- Activate when you arrive
Manual activation
- Go to Settings → Cellular → Add eSIM
- Select “Enter Details Manually”
- Enter the SM-DP+ address and activation code from your confirmation email
- Confirm and install; the profile downloads in under a minute
How to make calls with an eSIM in Puerto Rico
Most eSIMs on this list are data-only, meaning you rely on apps for voice and video calls. For most travellers this works perfectly. Puerto Rico uses the US phone system (area codes 787 and 939), so calls between the island and the mainland are domestic calls, not international.
For calls to local businesses, restaurants, or your hotel, use:
- WhatsApp: widely used in Puerto Rico, especially among younger locals and tourist-facing businesses. WhatsApp calls work over your eSIM data at no extra cost.
- Jetpac Voice: call landlines, hotels, and restaurants directly without WhatsApp. Starts at $1.99 for 5 minutes across 50+ countries.
- FaceTime / Google Meet: works fine over 4G/5G in San Juan and across the island’s main towns.
- Regular phone calls: if your US carrier plan already covers Puerto Rico (most do), your native dialler works as normal. Check with your carrier before your trip.
If you specifically need a phone number with your eSIM, aloSIM includes one with every plan. Roamless also offers virtual numbers through its app.
Our final verdict
For most travellers heading to Puerto Rico, eSIM4 is the best all-round choice. It has the widest plan range (12 options from 1 GB to unlimited), the lowest starting price at $3.98, and a dedicated Puerto Rico plan that removes any confusion about USA coverage. Install it before you fly and you land at SJU with data already working.
If you are combining Puerto Rico with a US mainland trip, GigSky and Airalo both cover the island through their USA plans, saving you from purchasing a separate eSIM. GigSky is the better pick if you want unlimited data (starting at $3.99/day with a 2.5 GB daily full-speed cap). Airalo is the better pick if you want a polished app experience and the largest plan variety.
For the absolute lowest cost per GB, Roamless at $2.45/GB is unmatched, though its pay-as-you-go model requires estimating your usage upfront. Saily is the pick for privacy-conscious travellers who want NordVPN-backed security tools built into their eSIM app. Jetpac stands alone for keeping WhatsApp, Google Maps, and Uber working after your data runs out. And aloSIM is the only provider that includes a phone number with every plan, useful for car rental agencies and hotel bookings that prefer calling over messaging.
One important note: Puerto Rico is a US territory. If you already have a US phone plan, check whether it covers Puerto Rico before buying an eSIM. Most major US carriers (T-Mobile, AT&T, Verizon) treat Puerto Rico as domestic. An eSIM is most valuable for international travellers visiting Puerto Rico, or for US travellers whose carrier charges roaming.
Frequently Asked Questions (FAQs)
eSIM4 is our recommended provider for Puerto Rico. It offers 12 plans from 1 GB to unlimited, starting at $3.98, and connects through T-Mobile and AT&T for strong island-wide coverage. If you want unlimited data, GigSky’s USA plan covers Puerto Rico with unlimited options starting at $3.99/day. For the lowest per-GB cost, Roamless charges $2.45/GB with no expiry.
It depends on your existing phone plan. Puerto Rico is a US territory, and most major US carriers (T-Mobile, AT&T, Verizon) treat it as a domestic destination with no roaming charges. Check with your carrier first. If your plan does not cover Puerto Rico, or if you are travelling from outside the US, an eSIM is the fastest and most affordable way to get connected on arrival.
Puerto Rico eSIM plans start from $3.98 for 1 GB / 7 days (eSIM4) or $2.45/GB on Roamless’s pay-as-you-go model. For a typical week-long trip with moderate usage (maps, messaging, photos), a 3-5 GB plan costing $10-$17 is sufficient. Unlimited plans are available from eSIM4 (starting at $18.98 for 3 days), GigSky ($3.99/day), and aloSIM ($20.50 for 3 days).
Most likely, yes. T-Mobile, AT&T, and Verizon all treat Puerto Rico as part of their domestic network. Calls, texts, and data work the same as on the mainland with no extra charges. Some smaller MVNOs and prepaid plans may charge roaming. Check your specific plan details before travelling. If your carrier does charge for Puerto Rico, an eSIM is a much cheaper alternative to carrier roaming fees.
Most Puerto Rico eSIMs are data-only. For calls, use WhatsApp or FaceTime over your eSIM data connection. Jetpac offers voice calling to landlines in 50+ countries from $1.99 for 5 minutes. aloSIM includes a phone number with every plan. eSIM4 offers calls and texts through the companion Yabb app (paid add-on). Puerto Rico uses US area codes (787 and 939), so calls to/from the island are treated as domestic by most US carriers.
Most smartphones released after 2018 support eSIM technology, including iPhone XS and later, Samsung Galaxy S20+, and Google Pixel 3+. To check, go to Settings, then About, and look for an EID number. If it is there, your device supports eSIM. Some carrier-locked phones may have eSIM disabled; contact your carrier to confirm. All eight providers on this list work with standard eSIM-compatible devices.
Partially. Cell coverage reaches the El Yunque visitor centre and main parking areas, but signal drops to near-zero on most hiking trails (La Mina, Mt Britton, El Yunque Peak). This applies to all eSIM providers and all carriers. Download the trail map offline in Google Maps before entering the forest. Save any reservation or permit details locally on your device.
Hotels and Airbnbs in San Juan generally offer decent Wi-Fi, though speeds vary. Condado and Isla Verde hotels typically have the best connections. Old San Juan cafes and restaurants often have Wi-Fi, but it can be slow and unreliable during peak hours. Having an eSIM as your primary connection is more reliable than depending on hotel or cafe Wi-Fi, especially for maps, rideshare apps, and real-time navigation.
Our Methodology
Every provider on this list went through the same technical breakdown. We did not just install the app and run a speed test. We dug into the specifications that actually determine your experience on the ground.
Network carrier verification: We confirmed which local carrier each provider routes through by checking their live country pages. In Puerto Rico, all providers connect through T-Mobile and AT&T, but the distinction between dedicated Puerto Rico plans and USA plans that happen to cover the island affects pricing and plan structure.
Plan structure analysis: We compared data allowances, validity periods, pricing tiers, and per-GB cost across every available plan. We flagged hidden conditions like daily throttle caps on “unlimited” plans and checked whether unused data carries over or expires.
Feature audit: We verified hotspot support, activation method (QR code, app-based, or manual), multi-device compatibility, and whether each provider offers calls and texts or data only. We also checked for extras like built-in VPNs, phone numbers, or voice calling packs.
Coverage mapping: We cross-referenced each provider’s network carrier against published coverage maps to assess real-world reach in key travel areas: San Juan metro, Old San Juan, El Yunque, Rincon, Vieques, and Culebra.
Pricing benchmarked: We pulled current pricing from each provider’s website and compared equivalent plans side by side. The pricing tables in this guide reflect what you will actually pay at checkout, not promotional rates.
