Dual Sim

Depends on which country you bought the phone from. In China mainland, Hong Kong, and Macao, iPhone 12, iPhone 12 Pro, iPhone 12 Pro Max, iPhone 11, iPhone 11 Pro, iPhone 11 Pro Max, iPhone XS Max, and iPhone XR feature Dual SIM with two nano-SIM cards. This gives you two phone numbers to make and receive calls and text messages

Other models support a physical and a e sim.

Hope that answers your question.

Only models sold in China, Hong Kong and Macau will have dual sim capability. All other regions will have models with one eSIM, and one Nano sim slot.
