Network routing

T-Mobile Autonomous Systems

Autonomous Systems are groups of networks that participate in global internet routing. They are typically managed by companies, organizations, governments, or other entities. Each autonomous system is assigned a unique number that identifies them called an Autonomous System Number (ASN). When your phone connects to the internet, it's assigned an IP address that is managed by the autonomous system. The autonomous system then determines how that traffic is routed to and from the internet. Below are the autonomous systems used by T-Mobile for its cellular network.

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).

T-Mobile operates its own network. The company is owned by Deutsche Telekom AG.

The performance metrics summarize median download speed, upload speed, and latency from crowdsourced tests on T-Mobile's network. Higher download/upload and lower latency indicate a faster, more responsive connection.
