Do I need a separate SMS provider for production?

Usually, yes — for production you should use a real SMS provider rather than a fake/local-only setup.
Common setup
- Development/testing: use a mock service, local emulator, or sandbox mode
- Production: use a dedicated SMS provider like:
- Twilio
- AWS SNS
- Vonage
- MessageBird
- Plivo
Why you typically need one
- Deliverability: production SMS requires carrier-approved routing and sender registration
- Reliability: retries, delivery receipts, throughput limits, and failover
- Compliance: things like opt-in/opt-out, sender ID rules, and regional regulations
- Security: keep API keys and sending logic separate from non-production environments
- Cost control: production usage should be tracked and billed properly
Best practice
Use environment-based configuration:
DEV→ mock or sandbox SMSSTAGING→ sandbox or limited real sendingPROD→ real provider credentials
If you already have one
If your current SMS service has a sandbox/test mode, you may not need a different provider—just switch to its production credentials/configuration.
If you want, I can help you decide based on your stack (e.g. Twilio, AWS, Firebase, etc.).
