SMS Character Counter
Check your SMS length and segment count. Standard SMS is 160 characters (GSM) or 70 characters (Unicode/emoji). Messages exceeding this are split into segments.
SMS Character Limits
| Field | Limit |
|---|---|
| Single SMS (GSM-7) | 160 |
| Single SMS (Unicode) | 70 |
| Multipart SMS segment (GSM-7) | 153 |
| Multipart SMS segment (Unicode) | 67 |
| MMS subject | 40 |
| MMS body | 1600 (varies by carrier) |
Tips for SMS
- •GSM-7 encoding: 160 chars per segment (basic Latin characters)
- •Unicode encoding: 70 chars per segment (emojis, Chinese, Arabic, etc.)
- •A single emoji forces the entire message to Unicode (70 char limit)
- •Multipart messages use 7 chars per segment for concatenation headers
- •Each segment is billed separately by carriers
