I am repenting my decision to go for MTNL connectivity. Its extremely slow speed. If you are connecting to someone over voice chat, it will disconnect within few minutes and will completely spoil your chat. Keep on calling MTNL guys, and they hardly pick up their call. If at all they pick up, they talk in sarkari language as if we have done crime by calling them. We are facing problem for over several weeeks and no resolution. Now scouting for another ISP!
Recently we started receiving very high billing. We wrote a complaint to MTNL on this issue. After couple of weeks we got a reply from them that for all subscribers they have increased connection speed which means more bill! We were never informed about this. When told about this, they promptly replied that an advertisement was given in some newspaper informing public of this change.
I will advise everyone not to go for Tri Band unless you do not have any option and you like running after sarkari staff of MTNL.
