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)

​
Monitoring & History

Track your SMS activity in the dashboard:
  • Delivery status
  • Timestamp
  • Number of segments
  • Cost per message
