Network codes
US Cellular MCC-MNC Codes
Mobile Country Code (MCC) and Mobile Network Code (MNC) are unique identifiers assigned to mobile network operators. Together, they form the Public Land Mobile Network (PLMN) identifier that your phone uses to identify and connect to US Cellular's network. These codes are broadcast by cell towers and are used for network selection, roaming agreements, and regulatory compliance. This list contains the codes used by US Cellular that are currently in active use.

Network routing
US Cellular 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 US Cellular for its cellular network.

Across the United States, US Cellular ranks fourth of the 4 networks we compare on our overall rating. The carrier cards above put coverage, performance, and reliability side by side. The best network can change from place to place, so open your state or city page for a local pick.
Each carrier card has a five-dot rating for coverage, performance, and reliability, plus an overall rating. Coverage is how much of the United States the FCC reports as covered. 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. The overall rating weighs coverage 50%, reliability 30%, and performance 20%. 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 the United States. 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).
Smaller network providers are regional carriers or niche operators that serve specific parts of the United States or specialized customer segments. They still run their own networks but operate on a smaller scale than nationwide providers.
US Cellular operates its own network. The company is owned by T-Mobile US.
US Cellular has approximately 4.4 million subscribers as of 2025.
The performance metrics summarize median download speed, upload speed, and latency from crowdsourced tests on US Cellular's network. Higher download/upload and lower latency indicate a faster, more responsive connection.
