I have been using triband by mtnl for about a year now.
I must say that it is the best service provider in Mumbai.The speed is terrific, never experienced before.I have used many services before all failing to my expectation.Only Mtnl has provided me the speed which it promises.
For eg. I regularly get speed above 200KBps which is great.
A song downloaded under 1 min is common.
I also play multiplayer games online like cod4, halflife2 and never has my game lagged.Never.
In about a year or so, can u believe it my connection has never gone down.Never.
That is incredible.
*Billing is honest, must say.
Only the cost is high for ones who download more, considering they will get completion from airtel broadband they will reduce it.
Really worth it.
