The order, the delivery and the activation went very quickly and without any problems. This tariff corresponds exactly to my expectations. In particular, the monthly cancellation option I really like. So I do not bind myself two years. I opted for the O2 network and am also very pleased with the reception. Although you could also select the Vodafone network. Particularly pleasing was the very rapid activation of the SIM card. I can not say anything because I have not had him take over the service of the provider. All in all I am very satisfied and can only recommend DeutchlandSIM.
