Freedom Pop, ugh my experience with them has been one of bait and switch. I bought a hotspot from them and I ended up canceling a couple of months after that due to unauthorized charges and suspicious account upgrades.
To add insult to injury you have to call them to cancel your account something that took me hours to finalize.
The one bright spot is that their customer service do not contest at requests to drop fees/charges it must be a common request from customers
