@shahp00ja I just ran into this error myself so I'll just jump in here real quick. In order to send a test sms using the Twilio test numbers, you need to make sure you are using your test credentials. From the looks of this code it seems you may be using your actual credentials. To find your test credentials login to twilio.com and go to this link: https://www.twilio.com/user/account/developer-to
