You posted this in the Galaxy S6/S6 Edge space, but those phones don't support an SD card. Which phone do you have? If you have an S8, see if this helps:
We want to make sure that you are able to transfer your files, Alahef5. I do apologize, but what Tikibar1 stated is true. The Samsung Galaxy S6 and S6 Edge do not support SD storage devices. Please provide us with the make and model that you are using or post in the correct device model to get further assistance.
