A:AnswerTurn your phone off. Then pop out the SD/SIM card carrier using a paper clip, there should be two slots. One will be the SIM and the other empty. The empty one should be smaller than the SIM. If it is, it will fit. I have a Samsung A10e.
A:AnswerAs long as your phone supports MicroSD XC (it does), you should be fine. Technically you can expand up to 2TB with XC but that isn't currently available.
