Jio showing network but can't calls,activation
Jio sim showing network but cant call
Just insert ur Jio sim in sim slot 1
Because only sim 1 supports 4g lte
And sim 2 supports 3g.
After inserting it in sim slot 2 go to contacts and call 1977 it will automatically start.
After that sign up in my Jio app for using free
Internet and other facilities for 3 months
