How does Twilio's Free Trial work?

Twilio offers a trial to all customers who sign up, which includes a free balance for you to experiment with. When your balance is getting low, Twilio will send you an email with information to upgrade your account. 

Getting your Twilio trial going is an easy 5-step process. Below is a quick primer on setting up your trial number and some important development tips to make sure you build something amazing with Twilio.

Getting Started

1. When you sign up for a your free Twilio Trial, you’ll be asked to verify your personal phone number. This is an important security step that is mandatory to trying Twilio.

2. If you plan to use us for voice and messaging, please head here to get your first Twilio phone number after verification.

3. A shiny new Twilio number will be generated with its capabilities (Voice, SMS, or MMS) below it.

4. If the number doesn’t have the capabilities you are looking for (some numbers do not have all three capabilities), you can click the “Search for a different number” link to find a number that better suits your needs by the country or capabilities.

5. Once you have chosen your number, you’re all set!

Development Tips

These tips are very important to get the most out of your Twilio trial!

Phone Numbers
  • We only allow one Twilio number per trial account. To get a different phone number than the one Twilio assigned you automatically, you need to release the current number you have on the Numbers page first.
  • Phone numbers in Beta are made available to trial accounts. Check out this article on international numbers and their capabilities to find out which numbers are currently in Beta.
  • If you upgrade your account, your trial number will be carried over and charged monthly according to current Voice or SMS rates.
  • If your phone number is unused in your trial account for more than 30 days, we will have to remove it from your trial account. As you might imagine, we unfortunately do not have an unlimited supply of phone numbers for trial accounts. However, if you decide to return to your trial account, you can always buy a new phone number at any time and start using your new number, or if you are particularly attached to a phone number, you can always upgrade your account simply by adding your credit card.
SMS
  • Be sure to verify any non-Twilio phone number before sending or receiving any SMS messages to/from it.
  • You will be able to send SMS from your Twilio SMS enabled number, but not from your verified personal number. This rule will also apply after the trial.
  • Alphanumeric Sender IDs cannot be used with trial accounts.
  • When you send an SMS from your free trial phone number, it will begin with “Sent from a Twilio Trial account”. This message will be removed once your account has been upgraded.
  • You may be eligible to use Global SMS on your trial account. Find out more here.
Voice
  • Before attempting to call be sure to verify any non-Twilio phone number 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.
  • 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.
  • Trial Accounts can only use either your account’s Twilio number, or a Verified Caller-ID, as the Caller-ID/From number when making outgoing calls.
  • Calls to and from your free trial phone number will play a short trial message before your TwiML runs.
  • Calls are limited to 10 minutes.
Elastic SIP Trunking
  • You can fully configure an Elastic SIP Trunk for testing and placing actual calls to and from your business.
  • Trial accounts are limited to a maximum of 1 Outbound SIP Trunk.
  • Trial accounts are limited to a maximum of 1 Incoming Phone Number.
  • Trial Accounts can only use either your account’s Twilio number, or a Verified Caller-ID, as the Caller-ID/From number for Termination calls.

Video

  • There are currently no specific restrictions for video.

To start using your Twilio phone number without these restrictions, just upgrade your account.

If you are using Twilio’s Sandbox, read our FAQ on the restrictions of the old Sandbox.
