What ISP do you have that you can get upgrade to a business account with the same speeds for only $30 extra a month? AT&T would charge me $300/mo for the same speeds that I currently pay $80/mo for.
You are comparing the most expensive plan. This was probably 8 years ago so I’m thinking 10-15mbit. The business plan was the entry level one.
Generally they don’t care if it’s for personal use. I’ve heard of them shutting people down for something they saw as business related. They didn’t really get shut down, it was more like a friendly “We see what you’re doing and a business plan would allow you to do it for $30 more a month”.
