Hey, I have actually just bought an Mblaze connection yesterday after suffering with Reliance's poor data plans and absurd billing! My first experience about Mblaze is that its not as fast as Reliance. Plus, I have read a lot of reviews about MTS cheating on the 15GB thing on 999 unlimited plan (i.e., people suffering low speeds before reaching the 15GB mark!)
I have just bought this Mblaze thing as I atleast get 12 GB (its not 15 GB anymore) to play around, unlike other providers where I have no good data options. But sad to say, not very impressed with Mblaze.
The actual essence of having a broadband connection is not having to wait for the dialogue "Looking for...". When you have an actual fast broadband, your browser will not say looking for, but say waiting for!
I did a speed test of Mblaze on speedtest dot net and got disappointing results of only 300 kbps uplink and 70 kbps downlink. Severely pathetic as they advertise it as being 3.1 mbps (the practical closest to 3.1 mbps would be atleast 1.8 mbps). No luck!
As I said, any provider, you will have to suffer.
