Agree.
Earlier Mobile Office used to give a good experience but not now. Airtel has been facing severe problems now-a-days.
1) The Mobile Office speed is damn slow, than it was earlier. I have an EDGE enabled mobile, but still it sucks.
2) Very frequently the net gets disconnected for no reason.
Some other problems with Airtel :
1) Airtel deducted Rs.30 from my friends account inspite of he deactivating caller tune a month ago. This is seriously unfair.
2) Signal strength is very weak compared to Vodafone & other competitors. Just enter a basement or a secluded spot & the network bars vanish. I am using Airtel in Mumbai.
