Our coverage maps are high-level estimates when using your device outdoors under optimal conditions. Estimating wireless coverage and signal strength is not an exact science. There are gaps in coverage within our estimated coverage areas that, along with other factors both within and beyond our control (network problems, software, signal strength, your wireless device, structures, buildings, weather, geography, topography, etc.), will result in dropped and blocked connections, slower data speeds, or otherwise impact the quality of services. In addition, off-network 3G data roaming is not included in Lifeline and Prepaid plans.
The performance, coverage and speed of our 3G and 4G data networks are measured regularly in an effort to ensure our coverage maps are accurate and up-to-date. Coverage isn’t available everywhere, and speeds may vary considerably from averages when users are on a roaming partner network.
Services that rely on location information, such as E911 and GPS navigation, depend on your device’s ability to acquire satellite signals (typically not available indoors) and network coverage. E911 services also depend on local emergency service provider systems/ support. Estimated future coverage subject to change.
