“Cellphones, for many are life lines. They hold pictures, contacts, schedules, some even act as a mobile wallet.
“A telephone number is not considered Personally Identifiable Information under the law, so technically there’s not a legal obligation to protect that information.”
Companies use your cellphone to track your spending habits and also use it as your mobile identity. But this information in the wrong hands can lead to identity theft just as easily as your social security number.”
