4G LTE is a new and evolving technology and in some instances some 4G LTE devices may not connect to the 4G LTE network. If you see this device icon in the location popup detail click to learn more about your experience at that location. If there is no device icon, you're good to go!
In addition to showing our network technology in your area (e.g., 4G LTE), now you'll see the Verified Coverage icon overlaid when we have the majority of data connections from actual customers successfully connecting to the network, providing an added layer of confidence.
Network data is from customers' devices and through trusted third party apps. The data on the map is aggregated by location and not personally identifiable.
You can now see the entire 4G LTE footprint on the map at-a- glance along with the most comprehensive view of the network experience in your area with Verified Coverage using data from actual customers.
