The source of information by way a short post made on the official page of the Android Open Source Project (AOSP). "In general, some devices will be single SIM, even if they contain two SIM cards, as the Pixel 2018 case and that is a valid configuration".
This is news and it's not; the Pixel 3 line is technically dual-SIM, but the functionality is disabled in most markets. According to a source, the next-gen Pixel device will be coming with an improved dual SIM functionality. The most common is Dual SIM Dual Standby, wherein both SIMs are registered on the network at once, and both can receive calls / SMS, but generally only if the other SIM isn't already being used for that objective.More news: Kate Middleton’s BAFTAs outfit included a sweet tribute to Diana
Like those older dual SIM phones, the current Pixel use Dual SIM Single Standby or DSSS. So, the minute that you switch over to the eSIM, you're no longer able to make or receive phone calls from the number assigned to the physical SIM in your smartphone. This is how the Pixel 2 series and Pixel 3 series work, as both have a physical SIM slot and an eSIM slot. Most Android phones that support multiple SIM cards, as well as the iPhone XS and XS Max, use DSDS. You aren't required to purchase two identical phones to take advantage of the promotion, any combination of Pixel 3 or Pixel 3 XL phones will work regardless of their storage capacity.More news: Trump's racist Elizabeth Warren taunts have entered a new phase
