Seems so to me also. I am a user of Airtel's 3G services in Delhi. According to their promotions, there are daily 3G data usage packs, for example, there is a daily usage pack of 50 MB, which costs 5.00 Rupees. Though, the 3G speeds are expected to be as high as 7.2 MBps, which my handset supports, as it's a HSPA enabled device, I've never been able to make use of the whole 50 MB's, as the connection speed (download and upload varies between 3-10 Kbps). Whenever I've tried to use it, I've been able to use only about 12-15 MB's, and in extreme conditions about 20 MB's.
If Airtel's offering 3-10 kbps download speeds in 3G (rather 3.5G), it's just a waste of money investing in any of Airtel's plan. It seems to me that apart from their so called "FAIR USAGE POLICY", they are engaged in nasty tricks to cheat the consumers.
