How to Keep a Second SIM Active on Jio, Airtel or Vi

Start with your current plan

Open your operator’s app and check when service validity ends. Look for the cheapest eligible plan that explicitly includes service validity for your number. A data add-on or balance top-up may have different conditions.

Compare like for like

Check the number of validity days, incoming service, outgoing calls and SMS. Divide the price by the validity days to compare cost per day. Prices and eligibility vary by number and region, so use the details shown at checkout.

Keep your OTP number accessible

Set a reminder before expiry. After recharge, check the active plan and expiry date. If the number is linked to your bank and you plan to stop using it, update the registered mobile number with the bank first.
