SMS (Short Message Service) is a messaging channel that allows you to send image and text messages to users through their registered phone numbers.
Connecting the SMS channel to the Yellow.ai Cloud platform enables the following:
- One-way conversations: Send campaigns
- Two-way conversations: Automated responses and live agent support
- Send campaigns: Through SMS, you can send campaigns to inform users about discounts, sales, or special offers.
- One-way conversation: Supports one-way communication where only the sender shares information and recipients cannot respond. These messages include promotional offers, transactional updates, alerts, or notifications.
- Automated replies and live agent support: Enables automatic responses to user messages received via SMS and provides immediate assistance with live agents.
- Two-way conversation: Supports two-way communication, allowing both sender and recipient to exchange conversations. These messages can include messages such as live agent support, automated replies, order tracking, or feedback.
- Supported message types: You can use Text message type to send the SMS.
To send SMS using one-way or two-way communication depends on the regulations, guidelines, or requirements set by each country.
Limitations of SMS channel
| Option | Character limit |
|---|---|
| Text message | 160 characters |
Segment in SMS channel
A segment is a part of a text message limited to a specific number of characters, typically 160 characters in standard 7-bit encoding. In the context of SMS messaging, particularly in the GSM (Global System for Mobile Communications) standard, an SMS segment consists of up to 160 characters when using standard 7-bit encoding.
Key points about SMS Segments:
- Character limit: Each segment can contain up to 160 characters (7-bit encoding) or 70 characters (Unicode).
- Concatenated SMS: When a message exceeds the character limit of a single segment, it is split into multiple segments. These segments are sent individually and then reassembled by the recipient’s device to display as a single message. Some operators may send it as a single message without splitting.
- Each concatenated segment usually contains a few characters less than the maximum (for example, 153 characters for 7-bit encoding) to include information for reassembly.
- Cost implications: Each segment counts as a separate SMS for billing, so longer messages are more expensive.
