The screen says the code was sent, but the dashboard is empty. The most common mistake at this moment is pressing "resend" again and again; most services treat that as spam and lock the number temporarily. The reasons a code fails to arrive are limited. Walk through the seven below and you will find yours.
First, wait 90 seconds
SMS usually lands in 5–30 seconds, but delays between carriers can reach two minutes. The code appears live in your dashboard; no refresh needed. Do not request a second code before 90 seconds: some services cancel the first code when a new one is requested, and both get lost.
1. The number was already used on that service
Sign: Telegram says the code was sent to your app; WhatsApp says the number is already registered; Instagram silently rejects it. Cause: The service sends the code to the old account's open session instead of SMS, or refuses the number because its quota is used up. Fix: This number cannot proceed. Cancel the order, the charge returns to your balance, take a new number. Choosing countries with fresh pools lowers the odds.
2. The service flagged the line as VoIP
Sign: "This number cannot be used for verification" or "invalid number". Cause: Google, Instagram and TikTok reject internet-based lines. Fix: Use a real carrier line (non-VoIP); see what is a non-VoIP virtual number. All our numbers are tied to physical SIMs; if you still see this message, try a different country.
3. Your IP and the number's country do not match
Sign: Instead of a code you get an extra verification screen (photo, video selfie) or a "suspicious activity" warning. Cause: Connecting from Europe with a US number triggers extra checks on Instagram and TikTok. Fix: Pick a number from the country you are connecting from. Recommendations are in the country selection guide.
4. You hit the attempt limit
Sign: "Too many attempts, try again later." Cause: Too many codes requested from the same device or IP in a short time. The limit applies to you, not the number, so switching numbers does not help. Fix: Wait 1–24 hours. Do not buy new numbers in the meantime; you will spend money and hit the same wall.
5. The number was entered incorrectly
Sign: The service says the code was sent, nothing arrives, no error. Cause: Missing or doubled country code, or the number typed while another country was selected in the menu. Fix: Select the number's country in the service's menu and type the number without a leading zero. The dashboard already shows the number with its country code; copy it as is.
6. Call verification was selected
Sign: "We are calling you" or "voice code" screen. Cause: Virtual numbers do not receive voice calls. Fix: Always stay on the SMS option. If a service offers call verification only (rare), a virtual number is not suitable for it.
7. The message was lost in transit
Sign: The service says it sent the code, the window expires, no code, no error. Cause: A momentary carrier outage or a temporary issue in the provider's pool. Fix: The charge is refunded automatically when the window closes (refund policy). Take a new number from the same or a different country. If the same route fails repeatedly, switch country.
Quick checklist
| Symptom | Most likely cause | First step |
|---|---|---|
| "Code sent to your app" | Burnt number (1) | Cancel, new number |
| "Invalid number" | VoIP rejection (2) | Different country, non-VoIP |
| Selfie / extra verification | IP mismatch (3) | Country matching your IP |
| "Too many attempts" | Attempt limit (4) | Wait, do not buy numbers |
| No error, no code | Format (5) or delay (7) | Check the number, wait 90 s |
Frequently asked questions
Do I lose money when the code does not arrive? No. Orders with no code within the window are refunded automatically.
Can I request the same number again? The number returns to the pool; a new order gives a new number. Insisting on the same number gains nothing.
The code arrived but the service says it is invalid. The service probably cancelled the first code when you requested a second. Use the most recent code; if it still fails, start over with a new number.
Which services cause the most trouble? Google and Instagram are the strictest; Telegram and TikTok are more relaxed. Service guides: Telegram, WhatsApp, Instagram, Gmail.
