iPhone users on Verizon will be able to use FaceTime over 3G or 4G without additional charge, The Wall Street Journal reports. According to WSJ , all Verizon subscribers will be allowed to use “the data-intensive application with no additional charges, including those remaining on unlimited data plans.”

AT&T customers will have to subscribe to data-sharing plans if they want to use FaceTime over cellular. Sprint customers – although it may be impossible to use FaceTime over their slow network – will be able to use FaceTime over cellular without additional cost.
