Why avoid these mistakes when using disposable phone numbers?

Top 10 mistakes (and how to avoid them)
- Using the same disposable number for multiple accounts — rotate numbers and track usage.
- Ignoring expiration times — monitor validity and replace before expiration.
- Sharing numbers publicly or in insecure channels — keep numbers private to prevent abuse.
- Assuming every service accepts disposable numbers — check the platform policy before use.
- Not enabling additional privacy protections — combine masking with safe browser and device practices.
- Not testing the verification flow early — test scenarios including OTP delivery and delays.
- Using disposable numbers for high-risk apps — reserve for low-risk registrations and testing.
- Failing to manage logs and retention — handle logs securely and follow data retention rules.
- Ignoring legal or terms-of-service restrictions — stay compliant with laws and provider rules.
