I am a long time MTS MBLAZE user, its standards have gone down real bad. In the initial period of my purchase of Mblaze, it was fast. But later on it slowed down like hell. Previously I was experiencing 2mbps speed, whereas now 256kbps.
Actually my mobile 3G service is much much much more faster and its cost is less than Rs.200 a month whereas Mblaze, NOT less than Rs.400. Its plans were the ones that attracted me but I had to substitute it with my mobile internet :p
