No network when 3G or LTE selected

[breckjensen]

 
Hi,
  I have OPX and when i put JIO card and select LTE it gets network but when i connect to data it works for few mins or so and gets disconnected and have to put Airplane mode to get back data working and it keeps happening.
And when i put my vodafone sim and select 3G or LTE i don't get any network it gets network when i select 2G.
I have tried everything from flashing custom rom and unbricking method but nothing worked. If anyone can help that would be appreciated.
Please help.

Thanks!

I didn't find the right solution from the Internet.
