There are some rules for SMS and MMS in counting character per message as following:


The maximum number of character is 1600 characters
In case it exceeds 1600 characters, the error pop-up will show


The character limit for a single SMS is 160 characters, but the number of character is still depened on GSM and UCS-2 rules:

- GSM (without diacritics) : 160 characters

- UCS-2 including diacritics or special symbols such as emoji like this (^^): 70 characters


How to I insert real emoji/icon like this on message content, please refer to this article.
