SMS delivery statuses and credit counting

Delivery statuses

Every SMS you send appears in the history on SMS → Messages, where you can search and filter by status and date.

• Pending: the message was created and is queued for delivery to the carrier.
• Sent: the carrier accepted the message and sent it on.
• Delivered: the carrier confirmed the message reached the phone.
• Failed: the carrier could not deliver it, for example because the number is invalid or unreachable.

If you send through the API, you can receive these updates automatically with a webhook. See Send your first SMS with the API.

How many credits does an SMS use?

One credit covers one SMS segment. How much text fits in a segment depends on the characters you use:

• Standard characters (letters, digits and common punctuation): 160 characters in one segment. Longer messages are split into parts of 153 characters.
• Emoji and other special characters: 70 characters in one segment. Longer messages are split into parts of 67 characters.

For example, a 200-character message in plain text uses 2 credits, but the same message with one emoji uses 3.
