I wanted a Nanosimkarte with Congstar, and since I'm prepaid customer, I do not get. No way, I thought to myself, 'I do myself, but as I'm a S *** it I was looking specifically for a punch and was find him here. The adapter I could insert the existing Microsimkarte fit, push in the punch, punch and had a nano-SIM card. Granted, I still had to nachfeilen something. They did not fit directly into the Microsimadapter. But in the end it works now still, and that was the goal. Thank you, I can recommend this to anyone of the cutter does not want to force them to contract to ;-)
