Someone who is hellbanned suggested that the title is a lie, and this is only for their mobile hotspots - upon reading the notice, they're correct. People that have unlimited data on their mobile phone will continue to have unlimited data on their mobile phone. This only affects the mobile hotspot add-on.

>> There will be no change to your Mobile Hotspot add-on monthly recurring charge. Additionally, if your phone plan contains unlimited data, you will continue to enjoy unlimited data usage on your phone while on the Sprint network.
