When creating a username, Verizon sends a text message to the phone number you provided to verify the account. Once you complete your verification, log into the application with the username and password created. You can update your plan and check your bill with the My Verizon Mobile app.
You can also sign into your online account and use the My Verizon mobile website if the mobile application fails. Use the Verizon live chat support if you encounter issues logging into the application.Learn more about Mobile
