Indian telecom operators offer their services with 28 days validity instead of 30 days because they follow a 28-day billing cycle. This means that the billing cycle starts on the day the customer recharges their mobile account, and the validity of the plan lasts for 28 days from that date.
The 28-day billing cycle is a standard practice in the telecom industry, and it allows operators to manage their billing and accounting processes more efficiently. By using a 28-day cycle instead of a 30-day cycle, telecom operators can align their billing periods with the number of days in a month more accurately. This is because the number of days in a month can vary, and a 28-day cycle ensures that customers get the full value of the plan they have subscribed to.
Additionally, the use of a 28-day billing cycle also enables telecom operators to offer a wider range of plans with different validity periods. For example, they can offer plans with 7-day, 14-day, 21-day, and 28-day validity periods, providing customers with more flexibility in choosing the plan that best meets their needs.
Overall, the use of a 28-day billing cycle is a common practice in the Indian telecom industry and enables operators to provide more efficient and flexible services to their customers.
