Cheapest credible route for teams already on AWS — raw SMS pricing well below CPaaS rates, IAM-native auth, and no separate vendor relationship; fine for teams willing to implement their own OTP generation/verification logic.
Gemini Highly competitive pay-as-you-go pricing, deep native integration with AWS infrastructure (IAM, CloudWatch), and massive scalability.
Where AWS End User Messaging falls short, per the models
- Claude It's raw SMS, not a verify API — you build code generation, rate limiting, and pumping-fraud defenses yourself; origination-number provisioning (toll-free/10DLC/sender ID per country) is notoriously painful and support is minimal.
- Gemini Does not handle OTP state or code generation natively, requiring developers to write custom server-side validation logic and manually navigate carrier registration.
