Pixel 4 is First to Use Google Fi Dual Connect Technology

Posted on October 22, 2019 by Paul Thurrott in Cloud, Google, Mobile, Android with 10 Comments

Google revealed today that its Pixel 4 handset family is the first that can take advantage of Google Fi’s dual connect technology.

“Fi’s new dual connect technology, available first on Pixel 4, gives you even better coverage by connecting you to two LTE networks at once,” Google’s Dan Chak says. “This means that if you’re watching a video and Fi switches you to a better network, you won’t experience any delays or pauses—you won’t even notice.”

To date, one of the key advantages of Google Fi, at least on Designed for Fi devices, is that it can seamlessly switch between any compatible 4G LTE networks, whether they’re CDMA- or GSM-based. So this new capability obviously improves on that by offering simultaneous dual LTE network connectivity. It requires Dual Sim Dual Standby (DSDS) hardware.

“While one network is used at a time for sending data or making phone calls, dual connect technology improves your connection by keeping both networks ready for use at a moment’s notice, and allows for more frequent network switching,” Chak continues. “To use DSDS to connect to two networks simultaneously, Fi uses a SIM card and the eSIM at the same time.”

Google says that dual connect support will come to Pixel 4 as it becomes available over the next few weeks. It will come to other Designed for Fi devices later as well.

And it looks like I need another Fi SIM card.

    Can’t you use the eSim option on the Pixel 4? I did on my 3.

    "It will come to other Designed for Fi devices later as well"

    Does that mean it will come to the pixel 2 or 3 or only that it will come to future NEW phones like Pixel 5, 6 etc.

    I came close to going with a Note 10 instead of a Pixel 4 (the N10 might have been slightly cheaper with the generous trade-in on the P3XL), but I finally decided I really didn't want to lose full Fi compatibility and ended up going ahead and ordering a P4XL. This news helps me feel a tad better about the choice.

    But can this function as "European" style dual SIM? Means having in Pixel two Sims from two different carriers and be available/online on both simultaneously?

    This is great news. It wasn't that long ago I was reading an older article about why this would never be possible. The solution seems pretty obvious now that they're doing it, even if it isn't super elegant.

    That... is a pretty awesome feature... I hope it comes to the Surface Duo and that the Duo comes to Fi.

    DSDS = Deutschland sucht den Superstar (German equivalent of American Idol). :-D

    The pixel 3a officially supports this

    The pixel 3 does not. The Android 10 beta did have it turned on for the pixel 3 but turned it off right before it made Android 10 official
