most android and almost all iphones from my experience feature a form of tethering, which is using a cellular data line on a phone to share and provide internet access for other devices, such as laptops and sometimes desktop machines

for ios/ipad devices, this is called a 'personal hotspot', link at https://support.apple.com/en-us/111785, meaning if you have a 5g connection, you can connect your phone via usb or usb-c to a laptop, and have an internet connection, probably sans server capabilities, to do stuff like download files (including files from a unix or linux package manager) and browse the internet, you can also upload files, but latency might be high, so you really cant do stuff like play online games. but you can download them for offline use

heres the link for google smart phones: https://support.google.com/fi/answer/6182204?hl=en

you can connect over wifi or usb, and for linux atleast, i dont believe you can use a usb tether to do a fresh install of something like fedora, but if your operating system is already installed, it should be as easy as plugging in your devices via usb/usb-c, and the drivers should be detected and loaded by some kind of kernel mechanism, and you should be able to select it using a gui or command line tool, such as the gnome3 settings tool, or any settings tool in most modern commercial operating systes

this method is great for remote work, and as long as you have cellular data service, you should have a fully working, standard complient internet connection anywhere you bring your phone and other devices!
