Puerto Rico

Based on crowdsourced speed tests across Puerto Rico, T-Mobile currently leads in median download speeds. Open "See the numbers" on the carrier cards above to compare every carrier's speeds.

We aggregate speed tests from real devices in Puerto Rico and calculate the median download speed, upload speed, latency, and reliability values across all carriers. Reliability blends speed consistency and coverage quality to estimate how dependable a network feels in everyday use. Results update as new tests are submitted, and we typically update the values every week.

The network performance values summarize median download speed, upload speed, latency, and reliability across all carriers in Puerto Rico. Higher download and upload speeds with lower latency indicate faster responsiveness, while a higher reliability score indicates more dependable real-world performance.

Each carrier card has a five-dot rating for performance and reliability, plus an overall rating. Performance is the typical download and upload speeds and response time in real speed tests. Reliability is how fast the slowest 10% of tests are and how often tests connect, so it shows how a network holds up when it's busy. We don't have coverage data for Puerto Rico, so there is no coverage rating, and the overall rating weighs reliability 60% and performance 40%. A whole country takes in wide areas nobody lives in, so country-wide ratings are more lenient than the ratings on state, county, and city pages.

The reliability score in the performance section summarizes how dependable mobile performance is in Puerto Rico. It is separate from the five-dot reliability rating on the carrier cards. It uses a 0.0 to 10.0 scale (higher is better) and is calculated from real-world speed test percentiles with weighted components: download (50%), latency (30%), and upload (20%). It evaluates the lower-end experience using the bottom 10%, 5%, and 1% percentiles when enough samples are available. If local speed testing is limited, a coverage-based fallback is used from signal quality distribution (great/good/poor).

MNOs own and operate the cellular network infrastructure, while MVNOs lease access to those networks and sell service under their own brand. MVNOs have the same network coverage as the MNOs they lease from.

We currently are tracking 3 total carriers in Puerto Rico. There are 3 MNOs operating their own networks and 0 MVNOs.
