Backup Mobile Internet: Remain Connected or Disconnect

Peplink Balance One on 6.1.2

I have a failover to T-mobile USA using a Sierra Wireless 313U USB modem.

I’d like to set it up as “Remain Connected” but after about a day or so, the modem shows disconnected on the Dashboard. I’m not sure if this is happening because T-Mobile is dropping the connection or the Peplink is losing the connection.

When I set it up the failover as Disconnect (Cold Standby), it’s hit or miss whether the USB Modem connects or not.

May I know what is the connection status show in Dashboard for Mobile Internet? Only show Disconnected?

If Mobile Internet set as Cold Standby, traffics will not hit to it.
