Two esim cards in an iPhone 12 mini

Hi there Napaman26,

You can use multiple eSIMs on your iPhone 12 mini. Have a look at this information to learn more:

You can install eight or more eSIMs on an iPhone and use two phone numbers at the same time. 

What you need

* An iPhone XS, iPhone XS Max, iPhone XR, or later

* A wireless carrier or worldwide service provider that supports eSIM

* Your new iPhone needs to be connected to a Wi-Fi network.*

eSIM on iPhone is not offered in China mainland. In Hong Kong and Macao, some iPhone models feature eSIM. Learn about using Dual SIM with two nano-SIM cards in China mainland, Hong Kong, and Macao. For travelers visiting China mainland who wish to use an eSIM for prepaid data plans, these are offered by many worldwide service providers.

Take care.
