I am using jio connection last 10 months
when I got the connection signal strength was good but when I was make a call it said all lines are in this root is busy.
and data was very poor when I was download a file of 50 mb it takes approximately 10 to 15 minute
I was very apsad.
but as of now jio connection is leading mobile operator in india
every thing is very very good
call and data
if I download a 50 mb file now it takes on 1 to 2 minutes
I just want to say jio is very good operator in india as of now
so I strongly recommend to use jio connection.
