T-Mobile is sensing OTA software updates for OnePlus 8 devices on its network. This new update includes 5G support and two new frequency bands. You will not use these bands immediately, but at least when they are available, your device is ready. The update includes support for 5G bands 2 and 66, as well as bands 5, 41 and 71 that were supported at the time of release.
You can go to the device’s settings> system> system update> check for updates, and then check if the software is already available for your device.
