Yes it should work.
I brought sim with Samsung phone, used directly in one plus 3. All working perfect.
Follow televerificaton, install my jio app, register new number, verify email, install remaining apps , you will get 2gb data first and later unlimited..
Do it without worrying. Good luck...
You straight away put the sim in your OP3? What steps did you do after you got SMS on your alternate number?
