As you know Telecom operators have created a new rule by which you have to Recharge or Top up your Mobile number Every month, Otherwise The Incoming and outgoing calls will be blocked for you till you recharge.
Sounds weird, but that’s true, Don’t know why They Telecom operators like Airtel, Vodafone, Idea Created this. But you have to follow it. So I am sharing the Info about to avoid Incoming and Outgoing Service Blockage of your Mobile Number and Increase the Validity of Airtel SIM.
You have to Recharge with Rupees 23 to Increase Airtel Validity So you can Receive calls or Dial a call, send messages without any problem.
You can also do any recharge or net recharge of more than 23 Rupees in Airtel sim; This will also work fine.
Previously we have Shared How to Increase Airtel Data Validity.
You need to do the same recharge Every month to prevent blockage issue.
