two phone numbers

All apple iPhones since the iPhone XR and XS support dual SIMs, thus dual numbers. In China, Hong Kong and Macao iPhones accept dual physical nano SIMs. Everywhere else in the world, iPhones have a single physical nano SIM slot, and a programmable eSIM.

You can even program the eSIM with more than one number, but you can only use one eSIM account at any given time.

See -> Using Dual SIM with an eSIM - Apple Support

Use a physical nano SIM for one number, and get the eSIM programmed for the second number. Both can be active at the same time.
