Not receiving SMS verification code texts is one of the most common roadblocks when you sign up for a new account or log in. In most cases the problem isn't the number itself but a formatting mistake, a limit on the service's side or a short delay. Work through the steps below in order and you will solve most issues.
Not receiving SMS verification code? The most common causes
These are the main reasons a code never arrives:
- The number was entered incorrectly together with the country code
- The service is blocking too many code requests in a short period
- Temporary congestion on the carrier's or the service's side
- The service doesn't send SMS to numbers from that country
- A voice call or in-app verification was selected instead of SMS
9 fixes that actually work
1. Enter the number in the correct format
Typing the country code twice (for example, selecting +1 and then starting the number with 1 again) is the most common mistake. Pick the country code from the drop-down menu and enter the rest of the number without any leading zero.
2. Wait a few minutes
Some services send SMS with a delay of a few minutes. Instead of hitting "Resend" over and over, wait at least 1 to 2 minutes. Sending too many requests can trigger a temporary block.
3. Check the verification method
Some apps try a voice call or a notification on another device by default. If you see a "Send via SMS" option on the screen, choose it.
4. Try a number from a different country
Services deliver codes to numbers from some countries more readily than others. If you're using a virtual number and the code doesn't arrive, choosing a different country for the same service often fixes the problem right away. Our virtual number country guide explains how to choose.
5. Take a break if you hit a rate limit
If you see a warning like "Too many attempts," the service has temporarily limited you. Wait a while and try again. Connecting from a different network (for example, Wi-Fi instead of mobile data) can also help.
6. Update the app
Older app versions can throw errors at the verification step. Install the latest update from the App Store or Google Play and try again.
7. Check your spam and blocked messages folders
If you're using your own line, check the spam or blocked folder in your phone's messaging app. Messages from short-code senders sometimes end up there.
8. The number may have been used before
Some services won't send a new code to a number that was registered recently. In that case, repeating the process with a new number is the fastest fix.
9. Cancel the order and get a refund
When you get a number on OnaySIM and the code doesn't arrive within the set time, the order is canceled automatically and the charge goes back to your balance. If you don't want to wait, you can cancel it yourself and get a new number.
Tips for receiving codes with a virtual number
- Go to the sign-up screen right after you get the number, because numbers are reserved for a limited time.
- Don't request lots of codes in a row on the same number.
- Enter the code quickly once it arrives; some services' codes are only valid for a few minutes.
- For bulk workflows, you can read codes automatically with the OnaySIM API.
Common issues by type of service
The problem of not receiving SMS verification code messages can have different causes depending on the service. Here are the most common scenarios and practical tips for each.
Messaging apps
Apps like WhatsApp and Telegram apply a waiting period when many codes are requested for the same number in a short time. If you see a countdown on the screen, don't request a new code before it ends. Telegram sometimes sends the code to the app on another device first; tap the "send code via SMS" link to get a text instead. For service-specific steps, see our WhatsApp verification guide.
Email and search accounts
Services like Google may ask for a different verification method on sign-ups they consider suspicious, or show a warning that the number cannot be used for verification. When you see that warning, don't keep retrying the same number. Pick a new number or a different country instead. Our article on Google phone verification problems goes into more detail.
Gaming, shopping and social media platforms
These platforms usually send codes quickly, but they may limit repeated sign-up attempts from the same device. Clearing your browser cookies or restarting the app often helps.
Whatever service you use, enter the code as soon as it arrives: most verification codes expire within a few minutes. Learn more about how these one-time passcodes work.
Conclusion
When you're not receiving SMS verification code texts, first check the number format and the verification method, then wait a short while. If the problem continues, trying a number from another country or canceling and getting a new number is usually the fastest fix. Since orders that never receive a code are refunded, trying again costs you nothing.
