Puerto Rico

Based on crowdsourced speed tests across Puerto Rico, T-Mobile currently leads in median download speeds. Compare carriers in the performance table above for the latest results.

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.

The reliability score summarizes how dependable mobile performance is in Puerto Rico. 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.
