4G/3G/2G services of SIM cards require carrier support. Your phone's dual-card
slot supports 4G/3G/2G services. When two cards are inserted, the system
supports only one card's registered 4G/3G service. Your phone supports a smart
card switching function. If you need to change the card slot for the registered
4G/3G service, please go to Settings > SIM cards.
Do not insert or remove the Nano-SIM card while your device is powered on.
Doing so may cause permanent damage to your Nano-SIM card or device.
