I went for DOCOMO 3G as I had some critical work while travelling to mumbai and chennai.
I had taken the stick in Nagpur and to my utter surprise the stick didnt work in Mumbai and Chennai. When I contacted the call centre they told me I would get a 2g speed in roaming.
While buying the 3G stick I was told that I would get 3g speed where 3G is activated and 2G where there is 3G is yet to come.
But to my utter disappointment the stick didnt even give me 2G speed in Mum or Chennai.
The speed reminded me of dial-up internet which gave speed of 3-5 kbps.
What is pathetic is that when I called there call centre again the girl told me that Mumbai and chennai are not activated for 3G speed.
