Community Q&A
-
QuestionIf I block my number from displaying when making a call, can someone trace the call back to my phone anyway?Community AnswerNo, unless you call emergency services (but most don't allow the caller ID to be blocked).
-
QuestionI bought a prepaid phone under my Verizon plan, but my name is also on a family plan for Verizon. Can that plan access my private prepaid phone?Community AnswerProbably not. Most phone companies have their prepaid services separate from their postpaid (month to month) services. But I would recommend contacting Verizon to make sure.
-
QuestionWhy does anonymous show sometimes as restricted?Community AnswerThis sometimes happens because the person who is receiving the call has a whitelist - this means that only certain people have permission to call this person.
Warnings
