Just to save the anti-unlimited ding-dongs some time and trouble let me just say this:
There is no such thing as unlimited minutes or data. Last time I looked at a calendar there was no such thing as an infinite month. What store can I get one from? Maybe the same one that sells infinite hard drives.
Unlimited is just a marketing gimmick. Companies that sell these plans are frauds and thieves. Best to stay with a plan that provides specified limits, for example ATT with 2 GB limit.
But seriously, I have been with sprint for several years on their SERO plan at $30/mo, now $50/mo. I have used my phone as a (unofficial) hotspot using 10s of GB/mo on a couple of occasion (after moving and having no internet for a while)
