How can I go online as the administrator of my account and delete the stored txt messages there? Also I read that Verizon deletes them after a while but how long is a "while"? A billing cycle? What if I don't want anyone else who has access to my account to see my texts? I'm sure this is not just an isolated problem and many others have asked the same question.
You can not see texts context online. Only on the device. You CAN see a summary online if you are the account owner, the number a text was sent or received from and the date and time. But only for three months.
