The POCO X7 Pro adopts two Nano SIM card slots. The card slot is located at the left side of the bottom of the phone, when you face the screen.
For your reference, here’s more information about the Nano SIM:
1. A Nano SIM is the smallest SIM card size currently in use, measuring 12.3mm x 8.8mm x 0.67mm. It is designed to save space in modern smartphones, allowing the device to allocate more room for other components, such as batteries or processors;
2. The smaller size and lightweight design make Nano SIMs more practical and less intrusive, especially in slim and lightweight smartphones;
3. Nano SIMs facilitate the inclusion of dual SIM functionality in compact phones, allowing you to operate two numbers or carriers simultaneously without sacrificing space or design.
Note:
The POCO X7 Pro doesn’t support the SD card slot.
