SMS Capabilities

​

Requirements

To send SMS messages, you need:

• An SMS-capable phone number
• Sufficient credits in your account
• Proper automation flow setup

​

SMS Segments

SMS messages are split into segments:

• Each segment is 160 characters for standard ASCII text
• Or 70 characters for Unicode (special characters, emojis)
• Longer messages are automatically split into multiple segments
• You are charged per segment sent

For example:

• “Hello! How are you?” (16 chars) = 1 segment
• A message with 200 ASCII chars = 2 segments
• A message with emojis and 100 chars = 2 segments

​

Costs

SMS pricing varies by:

• Destination country
• Number of segments
• Type of content (standard/unicode)

​
