Hi we connect korea KT Data sharing Usim. but not used internet GL-Mifi-bc4

In other mobile phones, it became the Internet.

However, Internet is not available on Mifi equipment.

What do I need to see to see where the problem is?

Does it get IP address?
Can you change to tryUSB3?

I don’t get an IP address.

SIM card not registered are displayed.

Can you send details to support at gl-inet.com?

Pls include screenshot that show the modem modem and IMEI etc.

I’ve found a problem spot.

The LTE module’s band was not supported, so the search was not possible.

I checked the problem and ordered the EP06-e LTE module.

Thank you for your help.
