What card slot types does the Xiaomi 15 support?
The Xiaomi 15 supports two Nano SIM cards in its dual SIM slot, located on the left side of the bottom of the phone. There is SIM primary and secondary card distinction, which is a convenient feature if you need to manage two numbers. You can assign your best SIM card for data as the primary one. The secondary SIM card can just handle calls/SMS without using data. This flexible SIM card configuration allows you to easily switch between carriers or use one for mobile data and the other for voice services.
