What is Global SMS and how does it work?

Which numbers can send Global SMS?

Currently, Twilio offers Global SMS-enabled phone numbers in several countries. A list of these phone numbers can be found here.

Where can Twilio send SMS messages to and how much does it cost?

Twilio is able to send SMS messages to billions of people on over 1,000 carrier networks, in 150+ countries. To see if a country or carrier is supported, please visit our SMS Pricing Page and enter in the name of the country, then scroll down to the section labeled “All SMS pricing for” the country to see the carriers supported.

How can I get started with Global SMS?

  1. If you haven’t already done so, create a Twilio account. If you are offered a Twilio phone number, please be sure to select a phone number that has global SMS capability, such as a local number in United States or Canada.
  2. To use Global SMS, we recommend that you upgrade your account, but by following these instructions it may be possible to try Global SMS without upgrading.
  3. If you don’t already have one, please purchase an SMS-enabled phone number. You may not need a Twilio phone number if you plan to send messages using alphanumeric sender ID.
  4. By default, Twilio Accounts are enabled to send SMS messages to any supported country. You can double check the permissions on the SMS Global Permissions page.
  5. Try using our API Explorer to send a message. Simply fill out the required fields and click “Make Request”.

What format should I type the phone numbers in?

Please enter all phone numbers in E.164 format. No leading “0”s, no international trunk code, just a “+” followed by the country code, followed by the rest of the number.
