The lte on my phone stops working after about 15 seconds of inactivity.

In order to get it back, I would have to turn off the mobile date then back on.
I have a Note 4.
The problem doesn't happen when I choose "wcdma only".
Only with lte.

Sounds like a service issue

So what can I do?
I already contacted the provider and they said there is no problem from their side.

Contact tech support. If they still say there's no problem on their end, ask to speak to a supervisor. Then elevate it to level 2. Then a level 2 supervisor. Then either network or engineering, their choice. Eventually someone will know why it's happening. (If you don't push, they won't offer.)

(If this happened after an update, it may be a liability issue, and they'd have to repair or replace your phone, regardless of the state of the warranty.)
