SimSmsBox Quick answer: When Pinterest phone verification fails or rejects your number, rent an overseas real-SIM number on SimSmsBox, request SMS (not a call), and poll the code. Keep country near your IP; skip free public pools.
Pinterest often blocks VOIP and reused free-pool numbers during signup or when adding a phone for security. Here’s the receive-SMS path.
Why it fails
- Virtual / VOIP ranges blocked;
- Burned free-pool numbers;
- Number country far from your IP;
- Waiting on a voice call while rented numbers only get SMS.
