As for now, targeting is modest because of several privacy restraints. Federal Communications Commission (FCC) rules set limits for the use of location and other customer data. They also set other restraints, such as the ability of users to easily opt out of mobile updates anytime they want to. However, these standards can easily depreciate, and some suggest that unlimited texting for a flat rate contributes to this depreciation. Thus, companies such as Medio Systems, inc. are slowly taking steps toward that kind of targeting. This company supplies the search engine of many phones, including T-mobile. They implement targeted ads using cell phone search data and browsing. Someday, they will incorporate GPS-precise data for more precise targeting.
