A problem with Zyxel LTE5366-M608

maxg5

I bought a router Zyxel LTE5366-M608

I installed a sim card in the router. Only LTE network mode is turned on. Signal 4 divisions.

The problem is that every 3-5 minutes Internet access is lost. Helps restart the router.

Maybe something with the settings of the router?

 What could be my problem?

Here is the log of the router:
