Probably wouldn’t be a bad idea to get a VPN like NordVPN or Norton Secure VPN. I personally use Nord, but Norton is a lot cheaper for short term.
Also, you could consider a USB data blocker your phone can’t be hacked if you’re plugging in via USB. (doesn’t matter if you’re using your own power brick though)
