To my surprise, I checked today and I can enable my phone to be a Hotspot. In the past this option was disabled. Is this something AT&T has enabled for free or will I get screwed in the end using it?
I just noticed the hotspot is only when I'm on WiFi. If I have WiFi off, it won't work
That doesn't make any sense. Why would you need to use a hotspot only when you're on wifi? If wifi is available then you would just connect your other device to that rather than connect to your phone.
Anyway, I've been with at&t for over 3 years and have always had a hotspot available. I use it every night at work to tether my Chromebook & have never had an issue.
