The VoIP charges are over and above the fee that users pay Airtel for using data services. “However, in line with our philosophy of putting our customers above all else, we are committed to making VoIP services extremely affordable and attractive by ensuring adequate minutes for a very small charge on VoIP,” Airtel said in a statement. Bharti Airtel has tweaked its mobile internet usage and said that VoIP calls service will not be included in internet schemes that it offers and will be charged at standard data rates of 4 paise per 10 KB on 3G network and 10 paise per 10 KB on 2G network.

Based on standard rates, usage of each GB of data for VoIP on 3G network will cost about Rs 4,000 and while the same on 2G network will cost about Rs 10,000. As per estimates, usage of 1 GB data can entail voice calls of about 10 hours, depending on various factors including speed and network strength, while data usage could be much higher for the video calls. Skype and other such apps have gained traction in the recent past mostly because of such services being offered for free and users only pay for the data usage, mostly bundled with the internet package paid for them.

The company announced new schemes costing Rs 75 under which a customer can make 200 to 250 minutes long VoIP calls. The scheme will have 75 MB internet usage limit. At this rate, 1GB will cost Rs 1,024 which company otherwise sells for Rs 175 on 2G network and Rs 249 on 3G network.
