Currently, most mobile devices support SD cards, but there are still some Android devices that do not support additional memory cards because the device's ROM capacity is quite large. Therefore, if you want to buy a MicroSD card for your phone, you first need to check if your device supports SD cards. The simplest way to check is to see if there is an SD card slot on the side of your phone.
