Keep it short
A single SMS segment is a maximum of 160 characters, or 70 characters if you're using a non-Latin alphabet/character set. If you exceed this amount, your message contains, and is charged for, multiple segments, as indicated by the counter at the foot of the message. Adding elements like personalisation can vastly increase your character count, and therefore the cost to send.
The message is sent immediately. A confirmation page confirms the message has sent. The contact that you've sent to is added to your master Contacts list if they didn't already exist before.
Use our API
You can also send a single SMS message through our API, using the Send SMS message operation.
