Realme 9i does not compatible with PM network and I would avoid using it
it has one compatible band on 3G for voice, but PM is phasing that particular band (850) and using another one (1900) which Realme 9i does not have. So, you will have trouble with voice calls (it is not on PM's VoLTE list so it can't use VoLTE either)
for 4G , it hs only 1 compatible band for data. With just one band, it pretty much means it won't work most the time
