I phone 15 pro max sim cards

All iPhone 15 models sold in USA can NOT use a physical hardware SIM. They are eSIM only, there is no SIM tray for a removable SIM.

Please see details of appropriate models for each region in Apple's support document

iPhone - Supported 5G and LTE networks - Apple

Please be aware that the models available in each country may not include all versions and options.

Not when you buy the iPhone in the USA. USA is e sim only. For other countries, there will be a physical sim card tray

Not in the USA market.

In all other countries (excluding China, HongKong, Macao where iPhone 14 & 15 support two physical SIM cards, but no eSIMs) those models accept one physical SIM card and one (or more) eSIMs.

In the USA, iPhone 15 (all models) won't accept physical SIM cards, just eSIMs.
