As we are all doing the validity extension recharges for each SIM for the past few months. The private telecom companies made it mandatory to do minimum recharges every month to keep the number active. Here we are checking how to increase the validity of Airtel SIM with the validity extension recharges. Let us check the validity recharge for airtel and see what airtel incoming validity recharges are.
Update: The current minimum recharge with the smart pack is Rs. 79. The minimum recharge plan of Rs. 35 and the later Rs. 49 plan is discontinued.
Like all other telecom companies, Airtel users also need to use the minimum recharge plan or an unlimited plan every 28 days to get the incoming and outgoing facility on the number. Failing to do so will result in blocking Outgoing calls first, followed by the block of incoming calls, and finally disconnection of the number after a certain period.
