# 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)
**When to use**: ['Sending notifications to users', 'Transactional messages (order confirmations, shipping)', 'Alerts and reminders']
