The character limit for a single SMS message is 160 characters, however most modern phones and networks support concatenation and segment and rebuild messages up to 1600 characters. Messages not using GSM-7 encoding are limited to 67 characters.

When you send a SMS message that is over 160 characters the message will be split. Large messages are segmented into 153 character segments and sent individually then rebuilt by the recipients device. For example, a 161 character message will be sent as two messages, one with 153 characters and the second with 8 characters.

If you include non-GSM characters like eastern characters in SMS messages, those messages have to be sent via UCS-2 encoding. Messages containing any UCS-2 characters are limited to 67 characters and will be concatenated into 67 character message segments, even if the messages contain less than 160 characters.

We have your back! As you see in the screenshot above, when we detect any of these characters, we alert you and show you exactly how much each SMS will cost.

In the example above, each SMS sent will cost 3 credits. If we remove the emoji it will cost 2 credits.
