The thing you really have to be careful! It's quite a hassle, get the Nano SIM in there, because the Sim was slightly larger than the device with me. The insertion of the adapter into another phone without doing the Sim fell out again, was a real struggle. Which reminds me once the card is completely fallen out of the adapter, but the adapter slid me into the SIM slot of the mobile phone. The result was: They could not get him out !! He had hooked on the contacts! I thought the phone would be useless. It took me an eternity, it rauszubekommen there again! The mobile phone is luckily undamaged. However, after finally sometime adapter with simcard were together in there, but it has worked. The adapter thus serves its purpose, but the device is not optimal and therefore a very dangerous fight until then. Generally I would not buy this product, but rather try a different adapter, even if the price may be tempting.
