Just thinking about this- Effectively, this is zero cost per month (28 days). Now the Rs 20 recharge gives Rs 20 main talktime and 28 days validity. Note that the Main Balance validity in indefinite. Meaning, effectively cost is zero. You may accumulate this talktime in main balance forever, and later use it to activate any Service Validity Plan (Eg: Rs 35) or Unlimited Packs like (Rs 169, Rs 199, Rs 399) etc.
This move is certainly a damage control measure after Vodafone losing scores of subscribers due to non-recharge. What are your thoughts, guys? Do you think Airtel will follow suit?
