A map of T-Mobile's wireless coverage is accessible at T-mobile.com. The website features a searchable interface that displays the company's mobile and data service area dependent upon the specified address entered.
The map showcases areas that provide 2G/Edge coverage to the highest speeds available with the 4G LTE network. Data from T-Mobile's actual customers is comprised in the coverage map to show an accurate depiction of how service is received.
Calls are still capable in areas with low data speed connections by using T-Mobile's Wi-Fi calling option. Where T-Mobile service is not available, the company has partnered with other wireless providers to cover potential roaming occurrences for continued wireless access.
