SMS4Sats review
SMS4Sats provides temporary phone numbers for obtaining activation codes from online services. It exclusively accepts Bitcoin through the Lightning Network, allowing it to operate without requiring accounts or balances. Payments are conducted using hold invoices, which means the payment completes only when you receive the code. If the code isn't delivered, the funds will return to your wallet within 20 minutes at most. However, there's a limitation: once a number is used, it cannot be reused, even if a service requests verification again. In our view, SMS4Sats suits Lightning users seeking a one-time code.
ID rule not stated

How we read the terms
We do not give privacy services a score. We record what each provider's own pages say: when it asks for ID, the limits, who holds your coins and what it costs. Labels come from each provider's terms, never from our guess. How we read the terms
