# Message too long

## Error description

You're trying to send a message that exceeds the maximum allowed length.

Wavix supports:

* Up to **670 characters** for Unicode (UCS-2) messages
* Up to **1,630 characters** for GSM-7 (non-Unicode) messages

## How to fix it

Check your message length and encoding.

If you're not sure about the encoding, set the `smart_encoding` parameter to `true` in your Send message request. This automatically converts Unicode characters to non-Unicode equivalents to help keep your message within the limit.
