I'm planing to buy a USB Modem but was required to choose between ZTE MF190 or Huawei E173. I'm not very much an expert when it comes to USB modems, but I guess there specification are very close. I've been using an older Huawei E1550 which I lost earlier. It was very reliable and lasted long. So I guess the brand Huawei isn't so bad. Any experience with the ZTE?
