As usual with the UMTS Sticks of Huawei, there is the software to drive only on the device. In theory, that's good - plug in and you're done. In practice, unfortunately, a total failure. To me it was not possible to bring the stick to work with my Congstar map together - PIN entry impossible, tested on different systems. Even with the Sim deaktiverter PIN was not accepted.
Unfortunately, Huawei's too bad, offer software downloads on the internet. In conjunction with a PC the stick is accordingly not recommended.
The only consolation: the FritzBox the stick is working properly together.
