It's simple: the slot scheduled for the sim card simply not the sim card held in place because it is too large. I still fastened with glue, just to be able to place easily, but obviously, the glue was not strong enough for the sim card has still slipped. And surprise: the location can not remove the adapter! So I went as smoothly as possible but it has still hung two filaments that detect the chip. The result: a completely unusable slot. Thank you. Frankly THANK product which in addition to being more expensive than the competition (that is why I chose it ...) you destroyed your mobile phone.
