The Mac is a loaner, the iPad was purchased with grants, and I stupidly emptied my savings for the Watch, tv, and HomePod.
EDIT: even then, the Watch and tv were purchased used or on discount.
EDIT II: I shouldn’t have to explain myself to you. As an adult you should be able to understand and comprehend that, sometimes, not everything is as it seems.
I'm not going to defend ridiculously overpriced broadband, as it should be $40/mo, not $75/mo. But given that it is the way it is, you are clearly financially irresponsible, since you've dropped a bunch of money on crap you can't afford, yet you claim you can't afford to pay for a basic utility like internet. And what about the iPhone? What's your excuse for that?
Being financially irresponsible is not an excuse to abuse your cell phone plan for home internet, which you're apparently paying way too much for anyway if it's that big of a plan that you can abuse it like that.
It's a bit of a challenge to police, since AT&T doesn't necessarily know where broadband is and isn't available outside of their own wireline footprint, and LTE is great if you're in west bugtussle or east bumblefrack and don't have decent wireline connectivity, but it's not scalable to replacing home internet in areas that are wired.
AT&T and Verizon made a huge mistake by copying T-Mobile with Unlimited. They should have both kept things locked down with 128kbps hard throttles once you hit your plan allotments, and just nuked all grandfathered Unlimited plans. Then they could have sold rural internet access on a tower by tower basis, with only the nearby home tower(s) having Unlimited, and if the device roamed outside of those towers, it would get hard throttled after 5GB or whatever. Alternatively, they could have gone back to the Verizon Cantenna model for permanently installed LTE only in areas without wireline access.
You should be able to get an inexpensive pre-paid T-Mobile sim for your phone to try the service out with. Not as convenient as porting your number over to try, but you could swap sims at various locations for a few minutes and get an idea about signal, data, etc
I had one in my Moto G6 for a few days, not really long enough to see how it is. My point is, without grandfathering, people are much more likely to switch around more, increasing churn on all the carriers. I have a Sprint line free for a year on the G6 now, it's god awful.
