In accordance with the recent commit changes seen from the AOSP (Gerrit Open Source Project) Gerrit, the Pixel 4 may provide true dual SIM performance which will enable users to select which SIM they need to use for managing messages and calls. It’s thought that the Google Pixel 4 may bring support for Double SIM, Double Standby (DSDS) protocol which enables either of those two SIM cards for use for making calls or getting SMS, but not concurrently.
The Google Pixel two along with also the Google Pixel 3, together with their XL versions, technically provide double SIM performance as they encourage a secondary eSIM. But they follow the Double SIM, Single Standby (DSSS) standard, so the networks supplied by the physiological SIM and the eSIM cannot be in a functioning condition concurrently and just the support given by a single of them may be used at one moment. To the contrary, the vast majority of all Android smartphones from third party makers follow the Double SIM, Double Standby protocol, where, the support given by the SIMs is still live and users may define which one they would like to use for calls, SMS and information. It now seems the Double SIM, Double Standby attribute will eventually debut on Google’s smartphones beginning with the Pixel 4, that is allegedly codenamed’Coral’ and has been allegedly seen on Geekbench previous month.
In new AOSP Gerrit devotes which were seen by XDA-Developers, there’s a mention of incorporating property worth for identifying support for double SIM functionality. However, what’s worth noting here’s a remark with a Google employee in precisely the exact same thread that claims the 2019 Pixel will possess double SIM performance and it’ll differ from the execution on the Pixel 3 duo, where the double SIM performance is limited.
The newest developments indicate the Pixel 4 may introduce support for its Double SIM, Double Standby (DSDS) protocol through the eSIM + bodily SIM configuration, substantially such as the new strain of iPhones found in 2018. A case may also be designed for the coming of Double SIM, Double Active (DSDA) service about the Pixel 4 which allows utilization of telephony and information services of the SIMs concurrently, but it would depend if Google equips the Pixel 4 using double radios. Additionally, Google also seems to be analyzing the activation of the attribute for elderly Pixel tablets, but it can’t be stated with certainty if the service for DSDS protocol is going to be allowed for your Pixel 3 along with the Pixel 2.
