Hi there! I understand you're not receiving the verification code on the Trendyol app during checkout, which is essential for verifying your phone and completing the order. Let's work together to get this sorted out.

To help me assist you better, may I ask:
- Have you already checked your phone's SMS inbox and any spam or blocked message folders?
- Are you using a stable mobile network or Wi-Fi connection?
- Have you tried restarting the app or your phone?
- Is your phone number entered correctly in the app?

Meanwhile, here are some steps you can try:

1. Check Network and Signal: Ensure your phone has good signal reception or a stable internet connection. Sometimes poor connectivity can delay SMS delivery.

2. Verify Phone Number: Double-check that the phone number you've entered in the app is correct and includes the proper country code.

3. Restart or Reinstall the App: Close the Trendyol app completely and reopen it. If that doesn’t help, try uninstalling and reinstalling it to clear any temporary glitches.

4. Clear Cache (if possible): If you are using Trendyol through a browser on your Windows device with WebKit, try clearing your browser cache and cookies. For an app, clearing cache is typically done through phone settings.

5. Check SMS Blocking or Bank Blocks: Sometimes your bank or phone carrier may block automated SMS for security. Confirm with them if such blocking is in place.

6. Try Another Device or Browser: If you have another device or a different browser on your Windows 10 system, try completing the checkout process there.

If these steps don't resolve the issue, there might be a temporary service problem or an app-specific glitch. In that case, contacting Trendyol support directly via their help center or email [email protected] would be a good next step.

Would you like me to guide you in clearing your browser cache or any other step? Let me know!

Are you satisfied with the solution I provided so far?
