Many smartphone users in India prefer to keep two SIM cards—one for regular calls and data, while the other serves as a backup for emergencies. However, maintaining a secondary SIM can be challenging, especially after the recharge plan price hikes in July. To prevent disconnection, users often look for cost-effective ways to keep their secondary SIM active.
The Telecom Regulatory Authority of India (TRAI) has introduced a simplified rule to help users maintain their inactive SIM cards. As per the TRAI consumer handbook, a SIM is considered inactive if it remains unused for over 90 days. If a prepaid balance is available on the SIM, ₹20 will be deducted to extend its validity by another 30 days. However, if the balance is insufficient, the SIM will be deactivated, restricting calls, messages, and internet access. Once deactivated, the number may eventually be reassigned to a new user.
For those who accidentally leave their SIM unused beyond 90 days, there is a 15-day grace period for reactivation. During this time, users can contact customer support or visit their telecom provider’s store to restore their SIM without losing access to their number.

TRAI defines “non-usage” of a SIM as the absence of any outgoing or incoming calls, text messages, data usage, or interaction with value-added services, including payment transactions. This means that to keep a SIM active, occasional usage is necessary.
In a related update, Jio, BSNL, and Airtel users can now make calls even when their own network is unavailable. The government introduced the Intra Circle Roaming (ICR) facility on January 17, enabling customers to use any available 4G network in their area, thanks to Digital Bharat Nidhi (DBN)-supported towers. This ensures better connectivity, even in low-network zones.
