First, sign up for an account on Twilio. For this, you will have to verify your email and phone number. On a Trial period account, the number that you register and verify with, will serve as your To phone number where all your trial SMSes will be sent to. To get the From phone number, you will have to Buy a phone number from the Twilio console.
Don't worry when I say Buy a phone number. On a trial period account, you can Buy it for free. But obviously it won't allow you to send SMSes to custom numbers except the number that you registered your Twilio account with.
After you have signed up and bought a trial phone number, you can look at all of your credentials on the Twilio console here. You will require the following credentials:
- Account SID
- Auth Token
- Twilio Phone Number
The Twilio Phone Number here will serve as your From phone number. For testing on a trial account, use the phone number that you used to register and verify your Twilio account as the To phone number. For instance, on my .env file, I have set a TEST_PHONE_NUMBER variable, which will be the number that I have used to register and verify my Twilio account. On the other hand, the TWILIO_PHONE_NUMBER variable will serve as the To phone number.
