I am very pleased with the LTE stick. I use the Vodafone Internet Flat 5000 tariff, which provides LTE included. Start SAMSUNG Mobile Connection Manager, enter the SIM code and that LTE network is present, go with another software click instantly with high speed into the net. Technically it should be noted only that in the absence of LTE coverage, the SIM card has to be plugged into a UMTS stick to then dialing in via EDGE / 3G / HSDPA can, but this represents only 20s overhead.
