SMS UCS-2 and GSM encoding costs (Segments)

SMS rates are calculated per segment. Segments calculate the number of messaging chunks measured in bytes. For example, GSM encoding allows for 160 characters per segment, which means 161 or more characters create two messaging segments. 480 or more characters are three Segments, etc. Each segment of 160 characters utilizes 7 bits to encode. 

SMSes are subject to UCS-2 and GSM encoding based on the characters used in each message.

UCS-2 encoding allows for characters such as emojis but requires more data bits to encode (16 bits) and is limited to 70 characters. For example, a UCS-2 encoded message of 140 characters equals two segments. This would only be one segment with GSM encoding. Besides emojis, be careful with accented characters including accented characters such as ñ, à, and ö, but not including others such as á, í, or ú. Keeping text messages as plain as possible within the GSM basic character set can reduce the need for multiple segments.

Note - Encoding 'gotchas'
  • 1600 characters are the maximum limit for the entire SMS message. Message delivery may fail or an error may appear if this limit is reached.
  • The kinds of characters used in an SMS determine the encoding used (GSM or USC-2). Try to be cognizant of the characters used before sending messages. You can also use this segment calculator to check or test how messages will be encoded and how many segments they may use.
  • Hyperlinks, extra characters — as well as emojis — are counted as characters and directly influence segments.

See Segments for an in-depth explanation, along with how characters are encoded.

Voice input phrases

Certain nodes, like the Menu node, allow callers to say their option (e.g., "1, won, one") using the Voice Input Phrase field along with pressing their selection via DTMF (i.e., press 1). Voice entry utilizes voice recognition technology that is charged separately on top of other voice charges you may incur.
