According to the search results, all iPhone models that support eSIM can have multiple eSIMs and use Dual SIM with two active SIMs simultaneously.
The number of eSIMs that can be installed on an iPhone depends on your model and cellular plan.
The iPhone XS, iPhone XS Max, iPhone XR, iPhone 11 series, 12 series, 13 series, and iPhone 14 series (except for the models from the US) can support one eSIM and one physical SIM.
However, the iPhone 14 can hold up to eight eSIMs and dual active eSIMs, which means that you can have up to eight different eSIMs on your iPhone, and you can use two of them simultaneously for calls, messages, and data.
It is important to note that you might not be able to add two or more eSIMs from the same carrier.
