I am just thrilled ...
Before, I had taken my iphone, which, however, very often much worse than this network had Mifi ..
This Mifi I get partially shielded in buildings still 2-3g where my Iphone gets no more connection.
But much more convincing I find the Mifi on train rides since I came here never had such a strong connection had as this unit. Even in the ICE I gained very good experience (Of course, there is no permanent connection - but for surfing absolutely ok and all times better than the Telekom Hotspot)
The sharing function (eg SD card) etc I do not use ... However I had ever 3 people connected easily via the Mifi.
I give the thing is no longer out of his hands and recommend it clear! ;)
