The day after the purchase I had the documents in the mailbox. The request which includes the contract for number portability took a few minutes, and already three hours later I was in the mailbox pointing out that number portability would take place five days later. In fact, I could start calling with new SIM number and age on this day already from 9.30 clock. Great. A simultaneous contract for Lidl / Fonic for my daughter took three times as long. Having a VICTORVOX contract the same company only had trouble several years ago, I wanted to have nothing to do with Drillisch / Eteleon. But after several Discoplus- and three DeutschlandSIM tariffs in our family, I must now say that no other mobile operator offers such a good service. Everything is easy to do, even the termination is possible without complications via the Service pages. And questions about the contact were always answered no later than the following day. Who at Talkline as I had to wait several times two weeks on reactions or tried for hours in vain to reach the hotline; Who dared once in blau.de cancel and to recover his balance, which is like I feel in good hands with WinSIM or DeutschlandSIM.
