I am sitting in Tardeo right now, in my office. And haven't used 3G on my phone till today 
Waise are you sure it can be done through the exchange? I had gone to the Gamdevi Exchange,and they had no clue what I was talking about
Told me to do it online. But the "transaction fail" message pops up everytime. Tried a 50 Rs topup which happened fine. Don't know what the problem is. I have a prepaid connection btw.
Edit: Apparently some problem at their end. Told me to do it later.
