The following table lists the countries whose numbers are compatible to send SMS messages. These numbers will automatically be converted to E.164 format (normalized number), allowing SMS messages to be correctly delivered to subscribers.

Note that unsupported numbers are also accepted when provided directly in E.164 format: 

[+][country code][subscriber number]

Notes : 
  • The Country code is not required to be present in the number but if it is present it must be at the beginning. If it is not present it will be automatically added.
  • The Trunk code is a number that must be placed at the beginning of the number for internal calls within the country. However, it should not be included in the E.164 format.
