The Google Pixel 3 Duo is expected to receive a new software update which will add the LTE Band 48 connectivity support to both the devices.
Back in November 2018, Google had asked for a change for the Pixel 3 smartphone, now, the FCC documents suggest that the smartphone will now support LTE Band 48 following the software update that will be rolled out to both the Pixel 3 and Pixel 3 XL.
The FCC documentation suggests that the update will be rolled out to the device with model number G013A. This is the model number for the Pixel 3 smartphone which is sold via Verizon around the globe. It is not immediately clear as to when the new update will hit the Pixel 3 smartphones, however, we expect it to roll out sometime soon.
