Google Fi adds support for a second 5G network, won't say which one

Google Fi, the mobile virtual network operator launched by Google in 2015, has announced an upgrade to its cell service. The service, previously exclusive to T-Mobile's network, is now adding support for a second 5G network. However, Google has not disclosed which network it will be partnering with. Initially, Fi's service was designed to work on Google's Nexus phones, which would automatically switch between networks based on signal strength.

After T-Mobile acquired Sprint, Fi shifted to become a single-network service in the US, while still maintaining the ability to hop between networks for international travel. With this new super network feature, Fi will once again offer a dual-carrier service across the United States, allowing phones connected to the service to seamlessly switch between T-Mobile's 5G network and another unspecified 5G network to ensure optimal connectivity.

The announcement does not specify which 5G network Fi will be working with, merely stating that it will support two of America's top 5G cellular networks.
