Is there any difference between the main SIM card and the secondary SIM card in the Xiaomi 15 Ultra?

Question

Accepted Answer

In the Xiaomi 15 Ultra, there is no distinction between the primary and secondary SIM cards. Both SIM slots are identical, allowing you to insert two Nano SIM cards without any limitations on which one is used for voice calls, text messages, or data. This flexibility allows you to easily switch between SIM cards for different networks, roaming, or personal and work numbers. The lack of differentiation between the SIM cards ensures a smooth and simple experience when managing multiple lines, providing you with the convenience of dual-SIM functionality without additional complexity.
