Frequently Asked Questions

FAQ

  • Can I rent a number for less than 30 days?
    No. Our US plan has a 30-day minimum to keep your accounts safe during re-verification cycles.

     

  • How many SMS codes can I receive?

    Unlimited for normal 2-FA and account maintenance. Excessive bulk or automated spam is blocked under our fair-use policy. 

  • Is the number shared with anyone else?

    Never. Your SIM stays dedicated to you for the entire rental period. 

  • Will this work on Google or WhatsApp?

    Yes—our non-VoIP US SIM numbers pass Google, WhatsApp, and 1 000+ other platforms. 

  • What happens if an app rejects my number?

    Contact support within 24 hours; we’ll let you know how to proceed.

  • Do you offer pro-rated refunds?
    We don’t. You may cancel anytime, and the number remains active until the end of the current 30-day cycle. 
  • Why didn’t my SMS code arrive?

    Quick checklist

    1. Wait 60 seconds & request again - Some platforms send codes in batches; the second request often triggers delivery.
    2. Match IP & country - Many services flag mismatched geolocation. Use a U.S. IP when verifying with a U.S. number.
    3. Check device / browser reputation - If the site has flagged your device for creating multiple accounts or spam, it can silently block SMS.

      Fix: mask your fingerprint with a tool like Multilogin or a fresh browser profile.
