Hello
We purchased RUTX12 LTE Router in Korea.
There are three carriers (SKT, KT, and LG) in Korea.
Among them, two carriers (SKT, LG) are connected well, but one carrier (KT) is not connected.
I want to know how to solve it or why it is not connected.

Thank you.

Hello,

Thank you for contacting.

May i know if KT has good signals in that area.

Check if you are using the correct APN settings.

What is the firmware on the device.

Thanks
