Before that I had with my old Huawei E173 max. 4Mbps download. Now with the E392 I come with the same tariff to 10Mbps.
LTE has not been tested by me because it is not yet available in my region ..
The failure rate of my router is also lower than previously.
The only downside is that the stick LTE supports the high price, but what justified.
So I can only recommend this stick.
