Vpn server backup (static ip?)

With all the storms and internet outages past month, I need a reliable backup option to vpn server. If I get t-mobile static ip (I have business account) for the sim that’s already in my Puli, can I just disable vpn in the event of an outage, disable vpn kill switch, and use t-mobile roaming data (which is free for me). If I’m using this overseas, anyone know if static ip address is displayed? I know when I go to overseas, my phone still has t-mobile IP from USA. It has to do with t-mobile keeping track of billing I think.

For what are you using your VPN right now?

Using it for work

Will depend on the roaming contracts of your provider. It might be some US IP but don't need to. Would not bet on it - and of course, it depends on your country as well.
