INFORMATION ABOUT SAFEGUARDING DEVICES
5G: Devices operating on a nationwide 5G network currently use multiband dual connectivity, and receive service via both 4G LTE network and 5G network to support their connectivity. Dual connectivity could result in instances where the phone’s network indicator shows “5G” in a 5G coverage area, but the device is connected to the 4G LTE.
