Tata Docomo internet mystery

So one of my friend who lives in a hostel has a Tata Docomo connection that gives 10mbps with NO FUP and they pay 2000 Rs for it. Legit story, I checked everything.
I'm paying the same for 2mbps and 175 GB FUP on airtel.
I called them and they said someone will call me back and they did, but I was not able to attend the call, so does anyone have any knowledge about Tata Docomo?
Sorry for posting it in airtel section, didn't know where else to post, couldn't find tata docomo in the providers.

Couldn't find much on their website. It doesn't even list Chennai, but those guys are 100% using Docomo only

lol. 1700 gives 16mbit for 160GB.
The only 10mbit plan is for 3333. They are very much present in Chennai, mhsabir, iirc, had them for a while.

Yeah. I did have docomo for a while, even my signature is testament. But check availability as they are not present everywhere. A 0.5 km shifting of my house resulted me, in having to drop them.
As far as plan goes, I dont think it would be unlimited, unless they have started giving it as a hidden plan or something.

1700 for 16mbps and 163 GB is perfectly good deal for me considering the current price I pay. Okay, I will call them again tomorrow. Is there anything I can do to get them to call me quickly?
