Without eSIM! Rumors suggest that Google Pixel 4 may have support for two chips

On the one hand, more and more information appears indicating the arrival of intermediate variants of Google Pixel 3 and Google Pixel 3 XL, which can be called Google Pixel 3 Lite and Google Pixel 3 Lite XL and would still have the nicknames "Sargo" and " Pretty". But whoever thinks that Google is not working on its next flagship, it's wrong.

The first information about Google Pixel 4 begins to emerge, and they indicate that the next star of the Made by Google event will have dual SIM support. Previous leaks have shown Google testing a device with Snapdragon 855, 6GB RAM and Android Q. The information came from Gerrit platform, a free software for reviewing source codes.

It suggests that Google is adding new lines of code in the telephony framework and service to determine if a device has hardware support for multi-SIM features. However, the information that gives title to the text came from a comment within the forum.

Google Pixel 2 and Google Pixel 3 support the dual SIM in a way, but are limited to a standard SIM slot combined with an eSIM. These embedded SIMs, or SIMs built into the device, do not allow the use of the physical SIM network and the eSIM network at the same time. The Pixel supports dual SIM, but in single standby mode (DSSS), ie even if you have two SIM cards, you will not be able to receive calls or SMS in the inactive SIM slot.

Smartphones such as the iPhone and some Android phones support Dual SIM Dual Standby (DSDS), which allows the second SIM to receive calls or SMS as long as the SIM main slot is not being used for the same purpose. Finally, there is Dual Active Dual SIM (DSDA) support, which allows the two SIM slots to be used simultaneously for calls, data and SMS.

Comments on Gerrit suggest finding lines of code that will be used to "differentiate devices that support dual SIM mode, allowing those who do not, even if they can read two or more SIM cards." To do this, developers have written a function that returns a boolean, a value that becomes true in the case where "it is possible to use multiple SIM cards simultaneously to register on the network.

This is the function that anticipates the dual SIM features of the new Pixels. The documentation associated with your commit suggests that "Boolean value is required to differentiate the Pixel 2018 (which supports two sims, but in a limited way) from the Pixel 2019 (which will have dual SIM functionality)."
