Defending Digital Identity & Telecommunications Privacy
QuackSMS (hosted at quacksms.com) was founded with a singular conviction: your personal mobile number should never be a universal tracker exploited by data brokers, marketers, or malicious actors. We provide authentic, private cellular SIM routing across 190+ countries so individuals, QA testers, and software developers can verify online services without surrendering their real phone numbers.
Real Cellular Hardware
Unlike virtual VoIP numbers that are instantly flagged and blocked by WhatsApp, Google, and OpenAI, our platform connects directly to physical Tier-1 GSM cellular carrier infrastructure.
Zero-Log Architecture
We collect no government IDs, no KYC documentation, and zero personal residential data. SMS text payloads are ephemeral and permanently purged once your 20-minute session concludes.
100% Automatic Refund
You only pay for successful OTP deliveries. If carrier congestion or app delays prevent an SMS from arriving within 20 minutes, 100% of your funds are returned automatically to your balance.
Global Telecommunications Reach
QuackSMS maintains active cellular routing in over 190 nations and independent territories, including the United States, United Kingdom, Canada, India, Germany, France, Brazil, Indonesia, and Australia. Our automated routing engines continuously balance loads across thousands of SIM gateways to guarantee an average verification delivery speed of 12 seconds.
Who Uses QuackSMS?
Users seeking to prevent SIM-swapping attacks, telemarketing harassment, and unwanted corporate cross-site data correlation.
Software testing teams auditing SMS 2FA delivery gateways, onboarding funnels, and internationalized localized user registration flows.
Anti-Abuse & Lawful Compliance Standards
QuackSMS operates in strict accordance with international telecommunications statutes. We strictly prohibit our numbers from being used for financial theft, fraudulent banking operations, harassment, phishing, or illicit activities. We maintain real-time automated pattern monitoring and cooperate fully with legitimate telecom authorities to prevent fraudulent misuse.
