## Cost Considerations ## Cost Considerations
SMS messages incur costs per message sent. Consider: SMS messages incur costs per message sent. Consider:
- Using [SEND WHATSAPP](./universal-messaging.md) for free messaging when possible - Use `low` priority for promotional/non-urgent messages (may use cheaper routes)
- Batching non-urgent messages - Use `high`/`urgent` only when delivery speed is critical
- Using templates to keep messages under 160 characters - Use [SEND WHATSAPP](./universal-messaging.md) for free messaging when possible
- Batch non-urgent messages to optimize costs

## Summary ## Summary
SMS messaging in General Bots supports multiple providers with a unified interface. Configure your preferred provider in `config.csv`, then use the `SEND SMS` keyword in your BASIC scripts. For production, configure fallback providers and implement proper error handling to ensure message delivery. SMS messaging in General Bots supports multiple providers with a unified interface and priority levels. Configure your preferred provider in `config.csv`, set a default priority with `sms-default-priority`, then use the `SEND SMS` keyword in your BASIC scripts.
Priority levels allow you to:
- Use `low` for cost-effective promotional messages
- Use `normal` for standard notifications
- Use `high` for important transactional messages
- Use `urgent` for critical time-sensitive alerts
For production, configure fallback providers and implement proper error handling to ensure message delivery.
