Yesterday the Surf-Stick get delivered from the "wholesale / retailer Rafal Otto": It is suitable expressly 4G (LTE). So there is now a new generation! At first I was a little upset because a manual was to be found either on or in the packaging. However, it is "Plug 'n Play". So I boldly inserted the SIM card into the stick and this inserted into a free USB port on my PC. And lo and behold: Plug 'n Play's really true! The stick will be automatically installed (Driver), then automatically open the internet browser and displays in a new tab, the Stick menu. There I had to do is enter the PIN of the SIM card and presto-the-wupp I was on the Internet, and with full scale at the reception strength and 4G. The latter is of course always the place of residence and the location depends. So this connection is totally user-friendly and absolutely "suitable for beginners". The major network providers and their contract rates are automatically detected and preset in the profile due to the SIM card. Nevertheless, you can always create personal profiles and define them as standard. I really have tried several USB modems, but the HUAWEI E3131 is far spitzenmässig without competition, both by the operator, as well as the quality of workmanship. It really makes a quality impression. So, from me there's a full five stars and we can highly recommend !!!
