As much as possible I use my Mofi 4500 with a T-Mobile SIM for my RV’s internet connection. I use my 750 Slate for wireless device connection using Access Point using the 5G Wifi.
My iPhone service is through Verizon. When my T-Mobile service isn’t available I would like to switch to the Verizon USB tethering on the 750 Slate.
Is there a setup that would allow devices to always connect to the Slate but use the Slate’s USB internet when the phone is connected and the Mofi when phone is not connected?
