A:Answer No. MicroSD cards are physically much smaller than regular SD cards so the regular size (like this one) will NOT fit in a slot made for MicroSD. I don't know of any smartphone that uses the regular size SD cards, As far as I know all cell phones use the micro size. The micro cards often come with an adapter---a plastic "case" that looks like a regular sdcard and has a little slot a micro fits into so you will be able to use it in items that require a regular size SD card (like digital cameras). So, if you buy a microSD you aren't necessarily limited to using it only in a phone. But obviously doesn't work the other way---you can't get a regular size SD card into a micro sd slot!
