You can get a clear 4g unlimited for $30 a month (@ the same bp scammers)
Slightly OT, I tried out clear 4G a few months ago for $50/month. I didn't love the speeds I got at home and called to cancel my free 14 day trial.
I told them for the actual speeds I am getting I can find a ISP elsewhere for a lot cheaper.
They offered to drop my plan to $25/month for 3 months and said I can call every 3 month to extend the offer.
