I do not know, is why so often complained in the reviews here about the lack of operating instructions in German. My came multilingual (including German), have the device but just quickly done with the Quick Start Guide, which is written in English, but heh, even if you net the language is powerful, the images are enough. Establishment was quick and straightforward as a picture book, simcard was immediately recognized, but have now ne new, once Router Reset and indeed working again immediately. At first I have to puzzle a bit to get behind how I can represent my router interface not just on the laptop, but also on the I-PAD (if you want to receive SMS, ja ne interesting question) manual was there less ne help, google all the more. Battery life is impressive. Unit was definitely a sensible purchase decision.
