I bought the adapter, as I have temporarily used a spare was when my cell phone in the workshop. For this I have used the Micro-to-normal-SIM adapter. The adapter fits well in terms of size, although I fear that it is some space moderate somewhat scarce. If the SIM card has to be (with adapter) only inserted into the mobile phone (on flap - Insert SIM - flap), then this adapter is certainly very good. However, I had to push the SIM card. Since the adapter on the one side has a kind of film (thereby the micro sim not fall through) it is slightly thicker than the normal SIM card. The Ins-mobile-insertion was thus quite heavy. The problem was the removal: The mobile phone has owned a spring mechanism that would facilitate the removal. The SIM card slot was placed anyway incredibly disadvantageous. I have an hour hand to the SIM card to remove it because it was stuck by their incredibly thick in mobile. By brainstorming with family members I have very, able to try a lot of ways to finally really to remove the card again. Here, the adapter edge was destroyed. I've been using it: pins, crochet hook, scissors, needle, ... tries. Problem was in fact that the cell phone only minimal allowed space for the "access" to the SIM and therefore I could only use very narrow "tools". However, anyone who has a better constructed mobile phone should get with this adapter no problems. Through my bad experience was due to the overall thickness of the adapter with micro-SIM card, I have allowed myself to deduct two stars.
