Launch in a country
SMS requirements vary by country. Before you send to a new country, confirm which origination identities that country supports, whether the country requires registration, and whether two-way messaging is available. Requirements differ by destination, so plan for the country you are sending to rather than the AWS Region you send from.
To launch SMS in a country, follow these steps:
-
Look up the country in Supported countries to confirm it is supported and to see its origination identity options, registration requirements, and two-way support.
-
Request the origination identity that the country supports, such as a phone number or a sender ID. For more information, see Sender IDs.
-
If the country requires registration, complete the registration and wait for approval before you send. For registration details by country, see Supported countries.
-
Send a test message to confirm your setup, then move out of the sandbox to send at production volumes. See Move out of the sandbox.
For the full list of supported countries and their SMS capabilities, see Supported countries.
