Same thing happened to me yesterday. Got my new S7, while trying to install my micro SD card, the SIM card popped out of the tray and into the slot. Verizon was no help at all. Another cell phone/tablet fixit store said they would have to disassemble the phone. Nuts, I hadn't even activated the phone yet. I took a very small paper clip and straightened one bend. Then using a needle nose pliers, I made a 90 degree bend at the end of the straightened piece, only about 2mm long. I very gently got this bent portion behind the stuck SIM card and was able to pull it out. Card and phone both work fine. Hope this helps someone else!
