Hello, After a few weeks of use, I wanted to review this product because it is ruthlessly efficient! I have not ADSL and so I use the Huawei to my web consultations but also for my file transfers (mainly pictures of 4MB). The transfer is fast and reliable since we are talking about transfer via 3G and I got a peak time (18h-22h), via a recent shelf, over 40 photos (160MB) in less than 6 minutes . an average of 8 seconds per picture. Certainly it is the maximum speed of 3G but I never bug or cut / data loss. As for the "consultation surfing", consulting speed is comparable to ADSL. good product that I would not hesitate to recommend (but not tested in a non converte area 3G)
