Lebara is a scam. In Berlin, I bought their SIM with 7GB data, 500min call time and free calls to Germany. But... very soon I found that they charge if you call commercial landed or cellular phones. They give you 1€ on the SIM and after several calls to local shops, you can't call anymore. It supposes to be as to calling personal phones but they charge 0.19€ for commercial calls. I called and complained and they unsubscribed me from their site. Even calling to their customer support from the cell by number 5588 you pay 0.19€. Total scammers, don't buy their SIM.
