US carriers are simplest simply acquiescing the concept that of eSIM after a lot begrudging and skirting of the foundations. However having an eSIM on-board a telephone brings the potential for dual-SIM capability with only one bodily SIM slot.
Then again, we’ve simplest observed a few implementations to this point: Unmarried Standby, the place just one SIM card is used at a time for any goal, and Twin Standby, the place one SIM accesses knowledge, however each can take and make calls and SMS.
Sorry for the confusion, our earlier message will have to have mentioned you can not use the bodily SIM community and the eSIM community concurrently. Respect your working out.

We’ve observed simplest Unmarried Standby in use at the Pixel 2 and Pixel three sequence of units, each technically dual-SIM telephones with an eSIM and a card slot. However consistent with XDA-Builders‘s interpretation of recent Android Open Supply Undertaking code, we may be able to see the Pixel four undertake a brand new dual-SIM configuration the place each playing cards can be utilized for knowledge, calls and texts: Twin Energetic.
It will in the end take a 2d set of information radios to have each SIMs absolutely operating concurrently, however it sort of feels that devote messages are the use of language that suggest Google’s definition of a real “twin SIM mode” as both Twin Standby or Twin Energetic reinforce.
The boolean is needed to distinguish 2018 Pixel (which has 2 SIM playing cards, however twin SIM capability is specific to canine fooding) from 2019 Pixel (which could have twin SIM capability) […] Usually, some units might be unmarried SIM, despite the fact that they include two SIM playing cards, because the Pixel 2018 case and that could be a legitimate configuration.
On the very least, having the ability to take calls and messages from each to be had telephone numbers could be a just right get started for vacationers. At best possible, the Pixel four may just bond two mobile connections to achieve more potent obtain and add speeds.
However let’s remind ourselves that Android Q is poised to impose new carrier-locking choices for dual-SIM capability, so don’t hope for an excessive amount of.
