Does verizon show when messages are sent and or received, or can they be read on the bill? since its a 3rd party does it show up on the bill that its even being used?
It depends on the phone
if its truly a third party app that uses data connection like on an android phone there is no tracking at all. if it is an app from Verizon like on a lesser feature phone that used text credits then it would show up as a text message
