I use mts since last 1 year. when I buy the device starting one month I get frustated from the speed. it was about 15 kbps. aftr complainng th e spee was really gud to next 8 months. I was easily saw videos youtube. downloads are very fast as I accept.
but after that it get slow again I complain aain anad again but they did no responce. finally I shut down that device. I highely recomend peoples when you plan to buy a mts dongle. Cheak the area availibilty speed.
