I have two Sims . One is jio and one is bsnl. Jio being my secondary number but I use it for data so i recharge it every 90 days, I can't let it go because it's been the main contract number recently. BSNL is the longest one I had and it's on every banking and such important things, so I can't let it go too. But recharging it every month for 147 feels so extravagant. I just want that sim for OTP and incoming calls.

Is there a network operator I could port it into with better basic plans ?
