BSNL annual plan stays the cheapest way to keep a SIM active
BSNL’s long-validity annual pack remains the lowest cost-per-day option for keeping a number active, at roughly ₹3.3 per day — still well below the other operators’ keep-alive plans.

What to do
For a second SIM or a number you only need to keep alive, BSNL continues to offer the best value per day. Nothing changed this cycle, but it remains the plan to beat.
