Those plans are much better than plans that are strict cap and then no data, which are better than no limits but if you use more than your quota it costs a ton and by the way the usage information is delayed at least 7 days.

I do remember seeing the plans that said unlimited (tiny print slow after 30Gb) and that's misleading... better to put the 30gb in big letters, but I just want like 1 or 2 gb fast... Just switched to a hard capped plan cause it was half the price though and a higher cap and I haven't hit the cap in a long time.

I'm ok with that. I'm still on an old data plan that throttles me after I got the limit for high speed data. But they don't hide that limit or my usage, and it's really cheap.

I don't want to pay for unlimited data, and I don't want to lose data after hitting a cap.

Skype iirc used to have an "unlimited" talk time capped at some ten thousand minutes as fair use.

I am pretty sure even today if you have a phone call on Google voice that goes over two hours or so, your call will drop. I like it better this way because I can call back immediately after being disconnected.

The difference is that they are very reasonably up-front about "first X GB at 4G speeds" where the PTO thing is going to have a shrowd of mysteries and unwritten limits.
