Upcoming Pixel 4 Series Could Support ‘Dual SIM Dual Standby’ Technology, Allowing Convenience for Models Featuring Two SIM Cards
Having two active SIMs in a phone can prove to be incredibly useful as this functionality, among other things, can help you have separate numbers for work, friends, and family at the same time. Android phones have had this feature for a long time and last year, even Apple jumped on the bandwagon. Now it appears the Google Pixel 4 will also offer better dual-SIM support, according to the leaked code you’re about to see.
Pixel 3 Might Also Offer Better Dual SIM Support in the Future, Most Likely Due to a Software Update
According to the code and comments seen on the Android Open Source Project (AOSP) Gerrit, the Google Pixel 4 will let you use two SIMs at the same time. The Pixel 2 and Pixel 3 also offer dual SIM support but one of the two supported SIM cards is an eSIM which can be an issue if your carrier doesn’t support it. Moreover, the second and third generation Pixel lineup support the Dual SIM Single Standby (DSSS) technology which in layman’s terms means that you can only use the active SIM to communicate via calls and texts.
On the other hand, other Android smartphones and even the latest 2018 iPhone family come with the Dual SIM Dual Standby (DSDS) technology, enabling you to receive calls and messages on both the SIM cards, though not simultaneously.
So, basically, the Pixel 2 and Pixel 3 only let you use one SIM at a time but it seems like that would change with the Pixel 4. While the Google Pixel phones are usually considered solid devices, this was one limitation they had and better multi-SIM functionality will surely be appreciated by future customers. Apart from that, there is also a possibility that Pixel 3 is updated in the future to support DSDS.
The Google Pixel 4 is not expected to come out before October and November and there haven’t been many leaks about the device so far, save for one leak highlighting that Google could be testing it using the Snapdragon 855. However, common sense and the industry trend dictates that it will come pre-installed with Android Q and get its performance from Qualcomm’s latest and greatest SoC. The phone might also feature something along the lines of Apple’s Face ID, but it’s advised to take this info with a pinch of salt for now.
