I served the sim adapter microsim to serve me again from my old laptop samsung player star 2, time to fix my smartphone. The adapter does his office and it is not difficult to put or remove the sim card in it. However, putting all in my old laptop, it does not fit quite the same way as a normal SIM card since "all" is still jammed in the machine. Explanation: In this samsung, sim card is inserted on the side and remove it, simply push it a little more for it comes out a spring system. The adapter fits well but it is just sinking further when pressed. We do not feel an instant spring resistance. So to remove it no other way than taking a splinter forceps and remove it somehow what abysses and the adapter and the phone ... so bad. Blame it on the adapter? Thicker at very nearly q'une sim card? or the problem is specific to that phone? I do not have the answer. Anyway distrust.
