A single SMS segment generally equates to 160 standard GSM characters, but the number of characters you can include as part of one segment depends on whether or not you use Unicode characters in your message.
If your message goes over the character limit for a single segment, it’s sent, and charged, as multiple segments. To help ensure you don’t exceed your SMS send budget, you can set the maximum number of segments allowed in your SMS campaign.
When the segment limit is exceeded for a contact, for example, due to personalisation if they have a long name, the campaign send is skipped for that contact. You can view which contacts have been skipped in the SMS report.
