First, sign up for your free Twilio trial account. The signup process includes verifying your personal phone number: this is a security measure that is mandatory before you can try Twilio.
When you signed up for your trial account, you verified your personal phone number. You can see your list of verified phone numbers on the Verified Caller IDs page.
You must verify any non-Twilio phone numbers you wish to send SMS messages or MMS messages, or place phone calls to while in trial mode. This is an extra security measure for trial accounts that we remove once you upgrade your account. You may verify as many phone numbers as you like.
Click on the red plus (+) icon to add a new number:
Enter the phone number you wish to call or text from Twilio: Note You will need access to this device to receive the call or text with your verification code.
After signing up for your trial account, navigate to the Phone Numbers page in your console. You’ll see the phone number that we’ve selected for you — note the phone number’s capabilities, such as Voice, SMS, and MMS:
If you don’t like the number we’ve selected for you, you can search for another Twilio phone number instead.
Click on Search for a different number to find a number that better suits your needs. You can customize country, area code, or capabilities:
We only allow one Twilio phone number per trial project. If you select a number or choose your own and decide that you’d like a different phone number, you must first release your current number, then pick a new number from the Buy a Number page.
Click on the link at the bottom of the screen that reads Release this Number:
Once you’ve clicked the link, the number will be released, and you can get a new Twilio Phone number from the Buy a Number page.
You will not be charged for any numbers ‘purchased’ during your free trial: the billing cycle for phone numbers and usage only begins once you upgrade. You may see charges on your Project Usage page: this is just to give you a feel for our pricing and your usage. You will not owe this money once you upgrade.
Calls to and from your free trial phone number will play a short trial message before your TwiML runs. Within that message, we ask you to press any key to proceed with the call itself. Only after pressing a key will the code from your website will be requested. If you don’t press a key, the call will not connect to your code.
Calls are limited to 10 minutes while in trial mode.
You may make international calls from your trial account. However, you only have access to GA and Beta phone numbers. Check out the limited list of countries you can make calls to while in trial mode.
You cannot send SMS messages from your personal phone number with Twilio, whether on a paid or a trial plan. You can always send messages from Twilio numbers.
無料のトライアル電話番号からSMSを送信する場合、必ず冒頭に「Sent from a Twilio Trial account.」という文字列が追加されます。 アップグレードを行うと、送信時にこのメッセージは追加されなくなります。
While in trial mode, you can only send messages to non-Twilio phone numbers you’ve verified with Twilio.
While in trial mode, you cannot send messages using an alphanumeric sender ID
Ensure your trial number is SMS-enabled and not restricted to sending/receiving messages and calls from local numbers. You can see your phone number’s capabilities on the Phone Numbers page in the Console:This number is not restricted to domestic calls and messages and has Voice, SMS, and MMS capabilities.
Remember, you can only send messages to verified phone numbers when you’re in trial mode. Make sure you verify the international phone number you’re sending to in the Console.
Note: Trial accounts may only place Trunking calls TO and FROM verified numbers. Be sure to verify any non-Twilio phone 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. A purchased Twilio phone number also qualifies as a verified number you can use as the caller ID.
If your Twilio needs expand, or you need to accomplish something that isn’t available to your trial account, you’ll need to upgrade your trial account to a full paid account. All you need to do to upgrade is provide payment information — your credit card details or Paypal account — on the billing page. You can have Twilio automatically charge you when your balance falls below a certain threshold that you set, or you can buy Twilio credits with individual payments.
