Google's Fi service, which relies on networks provided by Sprint, T-Mobile, and U.S. Cellular, has received a few improvements over time, such as an enhanced network that was rolled out late last year. Now, the Mountain View giant is bringing dual connect technology to the network, specifically to Designed for Fi devices starting with the Pixel 4.
For those that choose to get Google's latest phone, the Fi service will now be able to connect to two LTE networks at the same time, making use of Dual SIM Dual Standby (DSDS) technology. This won't get you increased speeds, but it will improve your coverage, so if the service switches you to a better network while you're watching a video, you won't be interrupted while it happens. Since both networks will be readily available, the transition will be much more seamless.
As the name of the technology implies, using DSDS for this purpose requires a dual-SIM phone, and in the case of the Pixel 4, this is done using the SIM card and the eSIM simultaneously.
The new dual connect technology will be available in the coming weeks, and Pixel 4 devices will already be ready for it when it launches. Google says it will roll out the feature to more Designed for Fi devices in the future, though.
