So the Unlimited Choice has unlimited, but 22GB/line before it will then be throttled to "slow enough that you can't watch video or stream high-res music, but you might could stream some music" speeds. It looks like Unlimited Choice also slows even the first 22GB to a max of 3Mbps (possibly enough to stream Tidal decently.) It will technically be "unlimited" though, even after the 22GB. FWIW, 22GB is quite a bit on a phone, and I have to try to hit that. That's about what I use on an average month.
Unlimited Plus, however, gives you the same 22GB/line, but it's full speed (T-Mobile and Verizon tend to get 6-20Mbps around here, for comparison,) and it also gives you 10GB/line (I imagine this is included in the 22GB/line) of tethering/"WiFi Hotspot."
Al, how much data do you and yours use on each line at the moment? How much is the difference between Unlimited Choice and Unlimited Plus? Also, do you have TV through Direct TV or someone else? If you have DirectTV, there are some decent discounts you can work out with bundling it seems.
Also, Mike said they were going over the combined 30GB/mo.
Stretch, what are the details of your original iPhone plan?

P.S. I agree with Dan, I don't trust them, but I hate AT&T.
