iPhone 3GS - Airtel - Connectivity Problem

I took Airtel Rs. 98 Data Plan (2GB Free, Bangalore, Karnataka) on my iPhone 3GS. The plan is too attractive to be ignored. Now that I have been using it for a while. I have started facing problem with respect to connectivity. It does have the "E" symbol on top always, but in background, its good for nothing. The connection goes off and I do not get any notification for Emails and from applications like Facebook or Meebo.

Every now and then, I need to either Switch off and on the phone to get notifications, or I have to go to:

Setting -> General -> Cellular Data and reset the connection by swiping through Off and On.

This does resolve the problem. But its quite irritating, if you are expecting important emails and if you want to stay connected via Facebook or Meebo.

Now have moved to Airtel 3G plan (Rs.200 for 250 MB free usage). Not much to update on that as its been 2 days. Will keep you all posted.

Are you facing similar issues?

Now that I have used Airtel 3G for a month. I feel its the same issue with 3G connectivity as well. :( And the resolution remains unchanged; Cellular Date On/Off. Speed and coverage is not at all consistent, atleast in Bangalore.

The 250 MB limit is sufficient atleast for me, I just use "Facebook" "Meebo" and "All India News". Since I have Wi-Fi connectivity at home I end up downloading New Apps and Updates from there instead of 3G. That saves a lot.

I have already placed a request to discontinue with 3G and moving back to Rs. 98 Data Plan (2GB Free). Only if connectivity was consistent I would have continued, I didnt find any point paying an extra 100 buk.
