Google Pixel 4 could come with improved dual-SIM support

One of those might be changing in the upcoming Pixel 4 phone later this year and, no, it won't be the cameras.

In truth, the Pixel phones since the 2017 Pixel 2 actually have dual SIM support. ESIM is only used by a few carriers around the world, including Sprint in the USA, but it can act as a second SIM alongside the hardware SIM when activated. It doesn't have two main cameras nor does use the full extent of dual SIM capabilities. There is also DSDA or Dual SIM, Dual Active, which requires two different radios and allows the SIMs to be used simultaneously - but the smartphone industry mostly uses DSDS for dual SIM support on handsets.

We're nearly certainly going to get Android Q arriving with the Pixel 4, ready to take advantage of that dual-SIM functionality. You can make and receive calls and messages on both networks without switching as long as the SIM isn't being used for that same objective. DSDS is what's used by most dual-SIM Android phones and the newest iPhones; here, the second SIM can receive calls and texts if the main SIM isn't being used at that moment for the same objective. In other words, you can't have simultaneous calls on both SIMs (though why you'd want this I dunno).

As we've mentioned, not much is known about the Pixel 4 at this stage - October or November seems like a good guess for a launch date, sometime after the new 2019 iPhones have appeared.

Based on the Commit found on the AOSP page (see image at the bottom of this article), a Google employee says that Android Q will support Dual SIM, Dual Standby or even Dual SIM, Dual Active if the device and the carrier support it as well.

Although Pixel 3 supports dual-SIM, it does not feature proper dual-SIM support. So technically speaking, Google may be able to introduce real Dual SIM, Dual Active support for the Pixel 3 with a software update if the company wanted to.
