Other iPhone XS dual SIM - American & China SIM simultaneously?

[patent10021]

Do you think it will be possible to use a north American SIM + a China SIM at the same time?

It should work. It’s basically my current setup with my iPad.
I have T-Mobile e-sim, and a physical sim from Chinese carrier in my iPad Pro, i can just easily switch between 2 sims. No dual standby though

Here is the official support document on how dual SIM with eSIM works on iPhone Xs/Max
https://support.apple.com/en-us/HT209044

What you need

• A iPhone Xs or iPhone Xs Max with an update to iOS 12 coming later this year
• A QR code or a carrier app from a wireless carrier that supports eSIM*

To use two different carriers, your iPhone must be unlocked. Otherwise, both plans must be from the same carrier. If a CDMA carrier provides your first SIM, your second SIM won't support CDMA. Contact your carrier for more information.

For eSIM dual SIM, basically, you need to use the physical SIM for the Chinese carrier and activate eSIM for the American carrier.

When I roam in China which is all day and every day I can use all social apps without VPN since I am using a foreign SIM from a carrier which doesn't block IG, FB etc. Unfortunately when I want to use Mobike, and other Chinese apps that require a Chinese phone number I always have to swap in my China SIM. But then when I put in my China SIM those social apps are blocked of course.

I'm assuming I'll have the same problem WITH DUAL SIM/eSIM models.
