SMS/LMS/MMS
This guide covers sending text messages — short (SMS), long (LMS), and image (MMS) — to an individual or a group.
SMS/LMS/MMS types
The type is decided automatically
You do not have to specify a type. Bizgo processes the message as SMS → LMS → MMS automatically, based on the length of the content and whether an image is attached.
| Type | Maximum length | Image | Main use |
|---|---|---|---|
| SMS | 90 bytes | Not supported | Verification codes, short notices |
| LMS | 2,000 bytes | Not supported | Long announcements, detailed notices |
| MMS | 2,000 bytes | Supported | Messages that include an image |
One Korean character counts as 2 bytes, and one letter or digit counts as 1 byte.
When do you use each one?
| Situation | Recommended type |
|---|---|
| Verification codes, simple alerts | SMS |
| Order details, long notices | LMS |
| Marketing with images or banners | MMS |
| Failover where Kakao or RCS is not supported | SMS or LMS |
| Sending to overseas recipients | International SMS (see below) |
