Mystery 2G Network (404-00) Live over Kolkata.

Few days back my fellow twitter user Iman Aryon informed me about a new 2G network available over Kolkata - 404-00 or INA-00.

Earlier this code was allotted to MTS India in Rajasthan, we got informed by MTS that they are not testing.

Then who is it? We are yet to know.

In the mean time, ITU Mobile Codes says 404-00 is alloted to Dishnet Wireless/Aircel, Madhya Pradesh and Shyam Telelink/MTS India has 405-00 in Rajasthan.

As Airtel got 900MHz band spectrum in Kolkata in last auction, they could start 3G testing. (note that Idea will roll out 3G on 900MHz in Delhi in April, 2015) But then why it's showing 2G only.
So stay tuned, until we solve the identity of this network.
