Note the SIM card: it is a normal card is required. The stick can be seen, as the SIM is to be lodged. I had already set my Fritz box successfully for mobile with the Huawei E173, and had little doubt that it works with the stick. But it was no problem at all: Human pure - Stick in the Fritz box - finished. With us here in rural areas, the mobile is quite modest. With the cell phone I get ONLY Edge connection. The stick has a very good reception characteristics. A fast wireless network was immediately found (LED turquoise). Unfortunately I can not say whether it is a LTE or HSDPA network. For Speed: With the E173, I had about 3500 kbit, the Telekom stick I managed about 8500 kbit. These are fantastic values for this area here with me. For the software I can not comment because the stick at the Fritz box is. Ick can 100% recommend this stick further
