View text detail online with all phones on my account?
You can view the text message log when messages when sent and received and which number the messages were sent t or from. You have to log into the MyVerizon account as the account owner.
If you are looking for the actual content, you needed to be using the Verizon Messages+ app on all the lines and sync it with each individual MyVerizon login for each line. Otherwise you need to look at the actual phone.
