Seeking Help Please Suggest BSNL Alternative

[Endgame]

Hi friends,
I was using my BSNL since 10+ years. The last recharge I did was almost 5-6 years ago (approx ₹3K balance). As on date, the balance is ₹37 only. My primary number is Airtel for both data & calling. BSNL is used only in emergency and for bank OTPs. Didn’t find any cheaper plans to keep the SIM active only. So I’m thinking for a switchover. Please suggest me one.
TIA

After searching, found Plan 397 for 365 days unlimited call & data 2GB/Day!
This is bonkers, is it real?

dont make any recharge and . then u will see rs2 deducted on every 5th day, and validity gets extended by 4 days. this will allow u to make incoming ams and calls works smoothly.

Pv397, give 2gb and calling benifit for 60 days. and next 300, just incoming call/sms works, unless u have main balance for outgoing call/sms/data.
