Terms and definitions in messaging

Multichannel messaging service is based on a variety of telecommunication and Internet technologies. In the description of services, we often use abbreviations that may not always be known to you. Here we have compiled a glossary of terms and definitions used in the industry.

Delivery Receipt Error Codes

If an SMS message is not delivered (even after the SMSC retry cycle is complete) then a delivery receipt, with an error code indicating why the message failed will be sent. A complete list of Delivery Receipts can be found in our Developers Documentation.
