About speed
I have a 25mps plane, and I get download speed upto 3mbps awesomely awesome.
I have check speed on speedtest.net site they show down ode speed around 30 mbps and upload speed around 15mps.
About support
its good, I mean they receive your calls answer to them nicely. even takes action from their end if possible its provide whatsapp number also for register complaint .
I think you can give it a try buying small plan, once its ok, you can buy expensive plan from them.
best service best price they r giving us so many plan choices as per our usage.
great speed with reasonable price. network strength is also good.
