Twilio Communications

Patterns

SMS Sending Pattern

Basic pattern for sending SMS messages with Twilio. Handles the fundamentals: phone number formatting, message delivery, and delivery status callbacks.

Key considerations:

• Phone numbers must be in E.164 format (+1234567890)
• Default rate limit: 80 messages per second (MPS)
• Messages over 160 characters are split (and cost more)
• Carrier filtering can block messages (especially to US numbers)
