Phantom SMS

Phantom SMS is a developer tool that provides disposable virtual phone numbers and SMS APIs for testing OTP verification flows and SMS integrations without using real phone numbers. It is designed for developers and QA engineers who need to automate end-to-end testing of authentication systems, messaging features, or multi-factor authentication in staging and development environments. The project is interesting because it solves the common pain point of burning through real numbers or dealing with carrier delays during testing, offering a reliable, cost-effective sandbox for SMS-dependent features.
