Edit: Ignore my post, I was thinking about my cell plan
I haven't actually checked, but I have my doubts about "no data limits".
Where I live I have an "Unlimited" plan, which all the providers offer. It's "unlimited", but after [x]GB, they throttle you down to 512kbps.
Just want to say… even on the cell plan, AT&T stopped with the soft cap over a year ago in response to T-Mobile lifting theirs a few months prior. And Verizon then recently stopped theirs too.
