Coming to the Airtel's plan first, which comes at a price of Rs 198. Under this new plan, Airtel is offering 1GB of data to its users per day for a valid time period of 28 days. However, it is noteworthy that the new Rs 198 plan doesn't offer any voice calling facility -- which is supposedly one of the major thumbs down factor about the plan. Meanwhile, Airtel is also offering Rs 199 plan, which makes much more sense than its new plan. Airtel's Rs 199 offers 1GB of data along with unlimited calls to any network for 28 days.
