Oneplus 3T: Cellular data not suddenly stopped working on slot 1.

Cellular data suddenly stopped working on slot 1. It was working fine from last 1 month. I replaced sim to other phone and it was working fine. Then i placed sim in slot 2 and cellular data is working fine. Network is full and i can make call and sms but no cellular data. I did network setting reset. I tried safe mode and wipe cache partition but problem remain same.

What to do? I am really tensed as same thing happened with my Samsung galaxy s5. I thought it was handset problem so bought...
