Xiaomi may release a SIM card that can also be used as a microSD card

Although no many people find expandable storage of any use, a lot of people prefer to have a MicroSD card slot on a phone. Unfortunately, a lot of phones nowadays don't use this extra storage space. These manufacturers choose not to include the MicroSD card slot merely because it takes up precious space that could be filled by more important components.

Xiaomi though might have a different approach for this. Every smartphone uses a SIM card slot for the SIM, so why not have a SIM card that is also a microSD card. This will save the extra spaced needed for a microSD card slot taking up on your phone.
A patent found by IT Home shows how Xiaomi is working on the revolutionary storage technology that may end up the need for separate slots altogether. The card would have the usual SIM technology on one side and then storage technology on the other side. This would, of course, require a specialized SIM tray that can read both ends. The only drawback here is that only Xiamoi phones could use this kind of technology. As this technology is patent by the company.

It may seem like a brilliant idea but it might be too late. Since eSIM technology is going to be a more popular form of technology in smartphones, and there might not be even a space for a physical SIM tray the card in the upcoming few years. However, between now and then Xiamoi could entice people looking for expandable storage to buy its products.
