A US territory with full US infrastructure
Puerto Rico runs on US currency, US outlets, and US-grade cellular networks. That last part matters — wholesale data costs here track North American norms, not the broader Caribbean's, and it shows up as one of the lowest rates we offer in the region. The other side of that coin: if your home carrier is in mainland Europe or Asia, "domestic US roaming" through your carrier still bills as international. The eSIM sidesteps that.
Roamzy charges $2.25 per gigabyte in Puerto Rico, or $0.0022 per megabyte, billed in real time. No subscription. No expiry. One per-MB rate across 192 countries — that's the shape of the invoice, not a marketing line.
How much will Roamzy actually cost on this trip?
Visitor patterns in Puerto Rico are mainland-shaped: ride-hail across San Juan, Google Maps to El Yunque, restaurants and reservations through your phone, contactless payments in every café, the occasional video call. Plan on 1 GB/day on cellular:
| Trip length | Roamzy ($2.25/GB) | Tourist roaming pass | Local SIM at SJU |
|---|---|---|---|
| 1-day cruise stop | $2.25 | — | $15–25 + queue |
| 5 days | $11.26 | $30–80 | $25–45 + 30-day cap |
| 10 days | $22.53 | $60–130 | $30–55 + 30-day cap |
| 2 weeks | $31.54 | $80–160 (often two passes) | $35–65 + 30-day cap |
Competitor prices in columns 3 and 4 are 2025 ranges based on typical offerings; exact figures depend on your home carrier and the airport store you visit. Roamzy's rate in column 2 is our actual published rate from the pricing page.
A SIM at San Juan Luis Muñoz Marín runs $15–30 plus passport and a queue. On a one-day cruise stop the queue is the killer; on a 10-day stay the math is roughly even, but the eSIM saves the airport hour and starts the moment you land.
Where does Roamzy actually work on the ground?
- San Juan (Old San Juan, Condado, Isla Verde) — 5G across central districts, solid LTE everywhere else
- The cruise pier at Old San Juan — strong signal at the gangway
- The toll roads and PR-22 across the island — continuous LTE
- El Yunque rainforest — 4G near the visitor centers, weakening on the high trails
- Vieques and Culebra — workable 4G near towns and ferry terminals; remote beaches drop out
- Cordillera Central interior — 4G in towns, patchy on mountain roads
Puerto Rico is the densest cellular environment in the Caribbean. Real dead zones are rare unless you're hiking deep into El Yunque or kayaking far off Vieques.

What are Roamzy's honest limitations?
Three traps Roamzy doesn't have, because they were never built in.
- No welcome promo that bait-and-switches the second top-up. First top-up and twentieth bill the same per megabyte.
- No fine-print throttling on the cruise day. One rate, full speed.
- No auto-renewal you forgot to cancel before flying back. Balance runs out, the eSIM stops.
It's not a marketing gimmick — it's an engineering decision born from indifference to gimmicks. You can't make a tariff cheaper than no fine-print and no expiry — so we don't.
What if my trip extends to other countries?
- Dominican Republic — common pairing on Caribbean cruise routes
- United States — frequent connection through Miami or New York
