Please tell me how to permanently stop all texts.
You have a couple of options. You can log in to your My Verizon and go to parental controls and add a texting block or you can call customer service to add the block for you.
Parental controls cost $$. On my Verizon you can use "manage service blocks" to block all messaging to a particular line at no cost. On main page under I want to, more options, manage service blocks, block all messaging.
