Indeed, an update about an existing rule that the nation's telcos would completely implement has been given by the Telecom Regulatory Authority of India, or TRAI. All you need to do to keep your SIM operational without having the number removed from your name is pay Rs 20 a month. As previously said, this is not a new law, but it may eventually be implemented. The TRAI is ensuring that consumers are aware of these rules rather than paying more to keep using their SIM.
As you may already be aware, a mobile number stays operational for as long as it is recharged, and it has a 90-day window during which you may postpone purchasing a new SIM card before it is cancelled. The Rs 20 monthly balance, on the other hand, is invaluable since it lets you prolong this time by an additional 30 days. To maintain the SIM in your name, you may, for example, pay Rs 20 to extend the time if you don't recharge your phone for 90 days. You can do this each month.
