well using sify for some 6months now
ask ujwal too he to is a sify user
but we are broadband users
dunno which type you need
well if its broadband
then i say quite ok
more you pay more the better the product is
iam using thier 40kb package
speed wise its good consistent
earlier there were many problems
like it would get disconnected anytime etc
but now it seems to be solved
speeds are capped which makes sure you get what you pay for
its consistent through out the day no less no more in the day ot night
they have the dialer to connect to the net
which certainly needs some inprovements
but one thinkg annoying is that they force you to install a antivirus ratehr a stinger on your system without which you cant get on the net
the dialer checks that you have the stinger installed or not
but that can be solved out too
well i have tried some other company net packages
i.e pacenet
and exatt
found SIFY the best
so methinks you can go ahead with it
