what's sms4sats?

sms4sats is a privacy-oriented online service that enables users to rent disposable, one-time-use phone numbers for receiving SMS activation and verification codes from hundreds of platforms, including Twitter/X, Telegram, Discord, OpenAI, and more across 120+ countries. No user accounts, emails, or KYC are required—simply select a country/service, generate a Lightning invoice (~1500-4000 sats), pay instantly, and access the number via a unique URL. The service operates on a fully automated, non-custodial model powered exclusively by Bitcoin's Lightning Network for payments, ensuring sovereignty, low fees, and anonymity. Numbers are short-lived to prevent abuse, with options to send SMS as well. It emphasizes bot-friendly APIs and aligns with Bitcoin's ethos of permissionless access for digital agents and humans alike.
