Both card slots of Xiaomi 5 are Nano-SIM cards, and any card slot can be set as the main card. Support mobile, Unicom and telecom 4G+/4G/ 3G/ 2G. When the card is mobile and Unicom is 4G, the secondary card can support Unicom's 3G VoIP at most.

Xiaomi 5 dual-card users, if the secondary card is Unicom card, can support Unicom 3G online at most (full netcom 3.0 and above), and other operators can only support 2G online. Technically, it is not supported that two cards are online at the same time.

In addition, mobile phones can't hold two telecom cards at the same time. If you put two telecom cards at the same time, neither card will have a signal.
