What I found amusing was that Jio mentioned that their network is SA, but also said that it will work with existing SIM cards, which is technically not possible. They have implemented a combo core,
so the network will be using the 4G network control signaling (aka NSA) till they start issuing dedicated 5G SIM cards.

Also, I read somewhere that the minimum launch speed has been set at 100 Mbps (which will reduce with users), so 5G will be as ridiculous as 4G LTE was in India.
