Plivo API’s support sending SMS in all text based languages (e.g., English, French, Chinese, Arabic, etc.).


Messages containing only GSM03.38 7 bit characters have a maximum limit of 1600 characters. Messages longer than 160 characters are split into multiple message units, each unit consisting of 153 characters.


Messages containing one or more UCS-2 16 bit unicode characters have a maximum limit of 737 characters. Messages longer than 70 characters are split into multiple message units, each unit consisting of 67 characters.


Multi-unit messages are automatically stitched back together and delivered as a single message in countries where mobile networks support long message concatenation.
