Hello!
I have portable 4G LTE Router. It works fine until I travel to another country and my SIM card uses EU roaming. Then the provider is no longer shown on the display. Also at https://192.168.8.1/#/internet I get the error message "Unknown error occurred. Please check the network environment or reboot the device". And the "Cellular" tab remains empty.
System log shows:

I use VPN WireGuard Client.
I changed Wi-Fi Name (SSID) and password.
The Multi-WAN Interface Status Tracking Method are "Internet always available when the interface is connected".
MAC Address: Manual / Random
Schedule Reboot and Wi-Fi Scheduled Mode
"Switch TX Power" are ON.
My other settings remain default.
The errors remain after a reboot. If I reset the router, it works again but only until I change the country again.
Please help.
