Jio Network Bands: Band 3 Band 5 Band 40
Choose According To Your Region. In my region 3 and 5 working well.
You can select Two bands also because this device supports multiple aggregation. You can also set single band. It depends on you.
I dont know about other one plus devices but settings will be same.
