How does Twilio’s Free Trial work?
When you sign up for Twilio, you will get a free telephone number. Like all phone numbers from Twilio, it is “programmable.” You can build a web app that makes phone calls and sends SMS messages using this number. When people call it, you can have Twilio answer the call or dial another party. Likewise when, people send an SMS message to this number, you can have Twilio programmatically respond, based on directions you give us.
While we limit the number of calls and SMS messages trial accounts can make (and receive), just upgrade your account and add money so you can keep on making calls, sending SMS messages, and keep your Twilio number indefinitely.
There are a couple of restrictions that apply to trial accounts and don’t apply to upgraded accounts. Keep these in mind as you develop:
Voice
- There are a limited number of countries your Twilio account can make calls to. Upgraded accounts have the ability to enable permissions to call almost any country from your Twilio app.
- Before dialing a number from your trial account, you have to verify that number first by having Twilio place a verification call to it. This is an extra security measure that we remove once you’re calling from an upgraded account.
- Calls to and from your free trial phone number will play a short message before your TwiML runs.
SMS
- You must verify a phone number before you can send SMS messages to it from your trial phone number.
- When you send an SMS from your free trial phone number, it will begin with “Sent from a Twilio Trial account”.
To start using your Twilio phone number without these restrictions, just upgrade your account.
