Hi,i was planning to buy Huawei K4505 as my Huawei 1831 has gone bad. I would like to know from the owners of K4505 whether this modem supports QoS info displayed in MDMA software?also guys please let me know which is the best 21 mbps 3G modem available right now...both from the point of view of longevity and good speeds. i used to think that 1831 is the best bet but recent happenings have proved otherwise 🙁thanks
