Why is an Airtel minimum recharge necessary

Imagine your phone service is like a special club. To stay a member and keep using all the cool things like making calls, sending texts, and using the internet, you need to pay a small fee every now and then. This small fee is called a "minimum recharge." Airtel needs this minimum recharge to make sure you can keep enjoying their services. It helps them cover the costs of running their network and providing you with unlimited calls, data, and other benefits. For example, a ₹299 recharge might give you unlimited calls and 1 GB of data for 28 days! So, it's just a way to keep your phone active and connected.
