To receive incoming messages to a mobile phone number, you can enable mobile phone forwarding in your Texty Pro account. This will notify you of new messages even while not signed into your account. You must use a mobile number as the messages will be delivered as text messages. To set it up you must log into your Texty Pro account and update your settings.
You can enable it, disable it, and change the phone number as needed. You will receive a text message with the contents of the incoming message, but you must log into your Texty account to respond.
