Why SMS Messages Fail to Send from Zendesk
Why are my SMS messages failing to send from Zendesk?
SMS messages can fail to send for several reasons. Some common issues include the destination handset being unreachable, the phone number not supporting text, or the message exceeding the 160 character limit.
Additionally, if the end user has opted out of receiving messages, or if you've reached the limit of 500 daily, 1000 weekly, or 2000 monthly messages for US and Canada toll-free numbers, your messages may not send. Country-specific requirements for text messaging can also affect delivery. For more details, check out the originalZendesk article.
