I don't think airtel or jio will use n5 or n8 band or n28 for 5g in beginning 2 to 3 years may be after thatInstead of looking for number of bands, look for these exact bands...
Must have Bands:-
n40 (Jio planning), n3 (Airtel planning), n78 (All)
For Coverage:-
n5 (Jio), n8 (Airtel), n28 (All)
Good to have - But NOT a must:-
[1] n1, n41 (VoId if they get cash and ready to invest),
[2] There are some other bands like in 600MHz as well as n77 which will come for auction in India, but much much later.
[3] If buying ultra premium phone, look for availability of mmWaves support as well, not just for future proofing, but also for Intl Roaming.
