most cheapest and best for OTP mobile plan is from BSNLMe too recharged airtel for 1499/-..bcoz that number is linked to bank accounts and not interested in port out...
Keep main balance 100-200.
BSNL is deducting rs2 for 3days, but it actually gives 4 days. then on 5th day SIM goes to Grace period
again on 6th day rs2 gets deducted.
I enjoyed this benefit during 2020 lockdown.
1) Incoming sms ans calls works on all day, provided ur phone is in 2g/3g/4g network of bsnl
2) Make outgoing calls/sms on most days.
3) fo month of 30/31 days. total burning of money is Rs12 only.
4) also enjoy Full talktime from bsnl promo like rs100 FTT every sunday
5) Its kind of help in emergency , becuase u can activate any data pack like 16/98 etc ,which will be suitble on basic need on 3G network.
6) GSM network on bsnl is almost empty and now gives acceptable voice clarity and coverage.
