A recent FTC lawsuit says that Straight Talk, Net10, Simple Mobile, and Telcel America advertised unlimited data plans, but then slowed or cut off service for some customers once they reached a certain limit. The company that owns these brands, TracFone Wireless, has agreed to settle charges that its “unlimited” data claims were misleading and will pat about $40 millions to its customers.
