If you are still using a Plivo trial version, you can send a test text message to the phone number you used when you created your Plivo trial. In Tools > Edit Settings > Text Messages > Send Test Text Message, enter the phone number you used for your Plivo trial setup and click Send Test Text Message. Note: the option to send a test text is only available to users while in trial mode in Plivo. Add a credit card to Plivo to create a standard account for full texting capability.
