Jio 5g not working well even though signal numbers are good?

my jio sim just activated today but the 5g is soo unstable and literally not even working properly. my previous airtel sim had nearly same net monster app values it worked like hella fast ( 50gb download in like 30 minutes ), now this jio sim is strugling to reach 24mbps(3mBps), now I am getting standalone signals not like non-standalone signals like airtel but still jio 5g speed is nowhere near to airtel even with same netmonster app values? any possible solutions?
