Hi, in this small post. I'm going to show you how to take a sim card out of a Samsung Galaxy s5 mini.
I was finding this hard too. After pushing the sim card in I couldn't take it out, then I got this crazy idea. I couldn't believe how easy it was!
Just get a pin from somewhere, which is very easy to find I think. Then place the pin right on the edge of the sim. Then press a bit, not too hard you might damage your sim. Then push outwards as you can see in the picture above.
That's it, hopefully this helps you :)
