If you want to retain your Jio number but don't want to make Ambani any richer, here's a way 🧵
Acc. to Jio, they look for inactivity for 90 days (incoming doesn't count). This essentially translates to 90 days since the expiry of last recharge plan.
Means if you have a plan that ends this 15th at 9 AM, the 90 day window starts from the next second of plan expiry.
