Overview of the device.

Hab now 2 afternoons spent studying various offers for LTE router. It is noteworthy that in addition to the top dogs of AVM especially the Korean company Huawei, including the branded devices by Telekom and Vodafone is represented.

In order to facilitate the prospective searching I have down here once written an overview of the various routers.
It must be said that the original Huawei have all the features, but the branded appliances partly in the functional scope (usually rather unimportant functions) are circumcised. The advantages of the Telekom or Vodafone branded devices is in any case a German user interface, german manual and at least for the newer devices full telephone support by the manufacturer.

Huawei provides 5 devices during the Telekom and Vodafone have skipped a generation in each case:

Huawei B-390s 2 = Telekom Speedport LTE = Vodafone B1000
Huawei B 593u-12 = Telekom Speedport LTE II = Vodafone B2000
Huawei B-593s 12 = Telekom Speedbox LTE II =
Huawei B-593s 22 = = Vodafone B3000
Huawei B 5186s-22a = Telekom Speedbox LTE III = Vodafone B4000

(Typo may be retained; o). Note: the last generation Huawei B5186 and Vodafone are hardly available in Germany, as Telekom LTE III indeed available, but very expensive, hardly tested and probably involve me teething.

All in all is probably the Huawei B-593s 22 the penultimate generation the most recommended device.
