Why Your Verification SMS Never Arrives
Troubleshoot missing OTP codes on temporary and disposable phone numbers.
Missing verification SMS is common with temporary phone numbers. Apps like WhatsApp, Telegram, and major banks actively filter virtual and recycled numbers to reduce abuse.
Try these fixes
- Switch numbers - pick another active temporary number on the same country page.
- Change country - some apps only accept specific regions.
- Wait longer - delivery can take up to two minutes.
- Use service-specific inboxes - browse via Services so messages are filtered for your app.
- Retry off-peak - busy shared numbers can be slower.
If nothing works, the platform may not support public SMS numbers at all. Do not use Quick OTP for accounts you cannot afford to lose. See FAQs or contact us if you think there is a delivery bug.
