Twilio Trial Numbers
Twilio lets users try out its platform with a trial number. A Twilio trial number, however, is not sufficient for testing.
A number must be purchased from Twilio before messages can be sent or received.

If you'd like to test your flows before committing to a Twilio number, you can start with a Telegram channel, which is easy to set up and has free messaging.
