Encoding, length and concatenation

When using the standard GSM 03.38 charset SMS length will be 160 characters.

When requiring characters that do not exist in GSM 03.38, the SMS will be translated to UTF-7. This happens for example when writing in Russian, Arabic, Hebrew and other languages. When UTF-7, SMS length will be 70 characters

You can check your SMS length by using our Text Analyser API endpoint before sending or by implementing locally Google's phone lib utility.
