Bests & Worsts Reviews from Amazon

This GSM SIM card works fine on my Nexus 6, but be careful about what service options you sign up for, or it might not be free. If you sign up for FreedomPop, please be careful that you aren't suckered into unnecessary repeat charges. As part of signup (perhaps a different promotion), I had to take steps to downgrade my service, such as by removing a $3.99 "data roll-over" service/add-on. The user interface to do so is confusing, asking you multiple times whether you really want to deactivate that add-on service, requiring you to log in again, and presenting your options in a way that makes it easy to accidentally keep that add-on. I don't have screenshots, but I'm pretty sure the cancellation process included a giant "Cancel" button (bigger than any other option), that meant you are cancelling your "request to cancel" (not deactivating/cancelling the add-on itself). You have to look harder to find a tinier link that actually will accomplish the add-on's deactivation.. It's the kind of friction or "gotcha" user experience that you might expect from free or cheap services, but it does not garner trust, and makes it hard to recommend Freedompop's service.
