You need to get the Jio welcome offer invite to be able to get the 5G unlimited add-on. Ppl in the original launch cities haven't got it yet, I wouldn't expect Bangaluru and Hyderabad ppl to see it on the day of launch.
Starting November 10, 2022, Jio customers in Bengaluru and Hyderabad will receive the Jio Welcome Offer to experience unlimited 5G data at up to 1Gbps internet speed.
Just dialed 198 and customer support executive was like really, when did 5G launched in Hyderabad.
As per him, JioTrue5G Welcome offer is for all postpaid users and for prepaid with above 239 plan and they can't enable manually for particular user from the system.
