*** Update ***
VoLte got activated on my BSNL number after I complained to pgrms.bsnl.co.in. Now it’s not falling back to 2G-3G. Calls are crystal clear.
Also I find some websites which loads slow in jio loads faster in BSNL 4G internet.
So far so good. Now I’m conjecturing about porting my main jio number to BSNL.
Some testing still needs to be done about coverage details to most of the places I visit. After that I shall surely give a serious thought about porting my 7 yrs old main jio number.
So much fuss about tariff hike by pvt telcos.
