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.

SMS Message Length and Character Encoding

When sending an SMS message 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 (for example - emojis) characters are limited to 67 characters and will be concatenated into 67 character message segments, even if the messages contain less than 160 characters.
