Detailed provider reviews for Puerto Rico

Airalo

Recommended

Puerto Rico runs on US networks (T-Mobile, AT&T, Claro), which means Airalo's USA plan works here. You get the same reliable coverage as mainland US cities — 4G/5G across San Juan, the entire metro area, and most of the island. Airalo's regional plan also covers Puerto Rico alongside other Caribbean islands.

How much data do you need in Puerto Rico?

Puerto Rico has US-grade mobile infrastructure. Free Wi-Fi is available at many cafés, hotels, and restaurants in San Juan. Outside the metro area, your eSIM becomes essential for navigation, especially on winding mountain roads and coastal routes.

Our recommendation: 5 GB for a week of active island exploration. Puerto Rico rewards road-tripping — you'll use more data navigating than at a typical beach resort. If staying in San Juan only, 3 GB should suffice.

Light user (Old San Juan walking, hotel Wi-Fi): 2–3 GB/week.

Moderate user (road trip navigation, social media, restaurant lookups): 5–7 GB/week.

Heavy user (remote work, streaming, video calls): 10+ GB/week or unlimited.

Network coverage in Puerto Rico

Puerto Rico uses the same US carriers as the mainland: T-Mobile, AT&T, and Claro (a local carrier). This means coverage quality rivals major US cities. 5G is available in San Juan and expanding.

Excellent coverage: San Juan (all neighborhoods including Old San Juan, Condado, Santurce, Isla Verde), metro area, Ponce, Mayagüez, Rincón, Arecibo. 4G/5G with 30–80 Mbps.

Good coverage: Central mountain roads (Ruta Panorámica), Cabo Rojo, Fajardo, Luquillo. 4G generally available, may drop in valleys and tunnels.

Limited coverage: El Yunque rainforest interior (trails lose signal quickly), Vieques (coverage only in Isabel Segunda and Esperanza), Culebra (minimal — Dewey area only). Remote mountain peaks and forest interiors.

US phone users: If you already have a US carrier plan, your domestic data may work in Puerto Rico with no roaming charges — it's a US territory. Check with your carrier first before buying a travel eSIM. International visitors still benefit from an eSIM.

Tips for using an eSIM in Puerto Rico

Check your US plan first. If you have T-Mobile, AT&T, or Verizon, Puerto Rico is included as domestic — no roaming. Only buy a travel eSIM if you're visiting from outside the US or want a separate data line.

El Yunque offline maps are essential. The rainforest trails lose cell signal quickly. Download the area on Google Maps before driving up, and save trail maps offline.

Vieques and Culebra are connectivity gaps. These popular offshore islands have limited cell coverage. The bioluminescent bay tour on Vieques happens at night with no signal — embrace the disconnect.

Road-tripping the Ruta Panorámica. This scenic mountain route through the central highlands has intermittent coverage. Download your route and music playlists before starting. Gas stations along the way sometimes have Wi-Fi.

Old San Juan has excellent coverage. The colonial district has strong 4G/5G throughout. Perfect for real-time sharing of the colorful streets, El Morro fortress, and La Placita nightlife.

Frequently asked questions

Airalo is the top choice for international visitors to Puerto Rico. Since the island uses US networks (T-Mobile, AT&T), you get mainland-grade coverage. US-based travelers should check if their existing plan includes Puerto Rico as domestic before purchasing a separate eSIM.
If you have T-Mobile, AT&T, or Verizon, Puerto Rico is included as domestic use — no roaming charges. You don't need a travel eSIM. International visitors without a US plan should get an eSIM for data coverage.
Coverage on Vieques and Culebra is limited. You'll get signal in the main towns (Isabel Segunda on Vieques, Dewey on Culebra) but not on remote beaches, trails, or during bioluminescent bay tours. Plan for offline time on these islands.
Plan for 5 GB if road-tripping around the island (navigation uses significant data). If staying in San Juan only with hotel Wi-Fi, 3 GB is enough. Remote workers or heavy users should go for 10+ GB or unlimited.
Some providers include Puerto Rico in their Caribbean regional plans (Airalo does). However, since Puerto Rico uses US networks, a USA plan may offer better coverage and speeds. Check both options and compare pricing for your trip length.
