Good news is your speed improve very very much.(You will love me…sure)

Bad news is you might experience major outage in signal and you may not be able to  use voice calling.This is because of Jio Band using on your mobile.

A band is a network frequency at which a service provider offers connection. Airtel offers 4G on Band 40 (2300MHz), Vodafone offers 4G on Band 5 (850Mhz).

 Reliance Jio offers 4G on Band 3, Band 5, and Band 40.
In simple words

Best coverage: Band 5 > Band 3 > Band 40.

Best speed: Band 40 > Band 3 > Band 5

you will get best connection in the Band 5 but the speed will not be as good. And if you are on Band 40, you will get great speed but coverage will be poor.


A phone automatically switches between bands according to the strength of the signal at a certain location, which explains why Reliance Jio shifts from good speed at certain areas to poor at others.

— Dial *#*#4636#*#*
— Select phone information
