Can I use personal hotspot to get on the Internet on my computer?

Ok. I have a computer and want to connect to the Internet. Can I use hotspot on an iPhone to connect to the Internet. If so, how?

Yup that's pretty much exactly what "personal hotspot" was made for.

From the way you're wording your question I feel like you're talking about a desktop computer. If that's true, then you need to make sure the computer has a Wi-Fi adapter installed.

If it doesn't, you can buy a cheap adapter that plugs into your USB port for about $20.

Your computer would need Wi-Fi capability. If it's not built in, you could buy a USB Wi-Fi antenna. Also, I wouldn't do it unless you have unlimited data on your phone plan. Unless you don't plan on using it much.
