No, just get a 4G phone. 5G will take years for implementation. Considering how all telecom operators are in loss, I doubt they are enthusiastic about 5G spectrum auctions, upgrading equipment, etc.
Truth be told, India doesn't even have good 4G internet speeds. I used to get 7-8Mbps in airtel 3G years ago. Now depending on region & time, I sometimes get as high as 30Mbps, but usually upto 8Mbps, then there are some places where you don't even get 1Mbps consistently even though your signal strength is good.
