Reactivate sd card. I erased it by accident

Solution
Well, this right here, that you started, that is a thread.

In regard to 'reactivating' a SD card. Well you really don't activate those. You just plug them in, and the phone needs to accept it (sometimes it requires extra steps) and then you can copy photos, music, videos, etc., over to it.

Also if you erased a SD card, the data is most likely lost and you will have to start over. You can attach it to a computer and run some checks of the card and see if you can retrieve anything off of it, but there are no guarantees.

SIM cards, now those, on the other hand, need to be activated.
