In literally the devil ...

Got the adapter ordered to einzuzsetzen my nano-SIM in a Lumia 820.
The delivery took a few days, but then the adapter arrived. They are well made and seem to endure what. However, I have the SIM (mind you in the correct direction in the adapter and firmly pressed so that it sits well) then put into my 820 and had to find out that the Adapter + SIM was apparently too thick as it went sluggish than usual. When I tried to remove the SIM then, nothing happened more. The 820 has a click mechanism, but did not push the SIM out. It was only when I had the SIM then pushed in properly, they jumped out something. When then pull out the "surprise": not only the adapter and my SIM, but also equal to the contacts of the SIM compartment came with. Thus, my cell phone is no longer usable. Can I look at what I'm doing now.
So best not to buy, because apparently is the danger of destroying the SIM slot, but given. Dear request a new SIM or use the Stanzreste the previous, is safer by far. I had to learn it the hard way ...
