JACKSONVILLE, Fla. – Chances are you’ve been on the receiving end of them: unwanted political text messages that light up your cellphone at all hours of the day. But as a News4Jax viewer pointed out, the result is a seemingly endless barrage of text messages beamed directly to the palm of your hand. To keep your phone number from falling into the wrong hands, be careful when giving your number out. If you’re not sure how the information will be used, use your landline or a workplace phone number instead. Some providers, like AT&T and Verizon, are trying to keep tabs on political campaigns this year.
