Keeping node online while moving

Does anyone have ideas on how to keep a online while I am moving across the country? I can keep it powered up but I need help on keeping it connected. I have a Raspberry Pi 4 hardwired to a modem.

A simple 4G mobile connection is enough to keep it online.
Buy and setup a modem/router with 4G support, plug a SIM data (recommended unlimited traffic) in it and you can travel around with your node.

Thanks. I will check that out and get it set up.

Here is a link to help you connect your raspberry Pi to your router/mobile with the wifi.

Thanks, sabbatical, will check it out.
