Common questions

How does the SMS length calculator work?

The SMS length calculator looks at each character in your message to identify it’s encoding type and the overall message length.  Based on the encoding type and length, the total number of segments used is determined.

In our example image below, both messages in the GSM7 encoding type.  The message on the left has 157 characters, less than the 160 character for the first segment, so it is just a single segment.

The message on the right is a total of 173 character, pushing it over the 160 character limit, resulting in 2 message segments.

What does message encoding mean?

The SMS length calculator looks at each character in your message to identify it’s encoding type and the overall message length.  Based on the encoding type and length, the total number of segments used is determined.

The two types of SMS encoding used by Sakari are:

  • GSM-7 Encoding – GSM7 is the encoding type most commonly used, and supports more than 128 commonly letters and symbols. Each segment is limited to 160 characters maximum.
  • UCS-2 Encoding – UCS2 uses 16 bits to encode each character. Each segment is limited to 70 characters maximum.

How will my text message be encoded?

When you send SMS messages with Sakari, we will automatically use the most compact encoding possible.  If you only use GSM-7 characters, your messages will be encoded at GSM-7.  If any non GSM-7 characters are included, your entire message will be encoded at UCS-2, which limits each message segment to 70 characters each.

What is a message segment?

Text messages are measured in character batches called segments.  Segments are typically 160 characters or 70 characters, depending on the encoding type. 

How are SMS messages billed?

Using Sakari, your per message rate is based on three different criteria:

  • The length of your message in segments
  • The destination country of the recipient
  • Your messaging plan
