Step-by-Step Solutions to Fix Missing SMS Verification Codes
1. Use Voice Verification Instead
OKX offers a voice call option as an alternative to SMS. If your mobile network isn’t delivering texts reliably, switch to voice verification:
- On the verification screen, look for the option that says "Receive code via call" or "Voice verification"
- Confirm your registered number
- Wait for the automated call and note down the code
This method bypasses SMS delivery issues entirely and works well in areas with weak text messaging infrastructure.
2. Check Your Email for Backup Verification
Even if you’re expecting an SMS, OKX often sends duplicate verification codes to your registered email. Always:
- Open your inbox (and spam/junk folder)
- Search for emails from [email protected] or [email protected]
- Look for subject lines like “Your Login Verification Code” or “Account Security Alert”
Email-based verification is especially useful if your mobile number has changed or is temporarily unreachable.
3. Assess Your Mobile Network and Signal Strength
A weak or unstable signal can prevent SMS delivery. To rule this out:
- Move to an area with better reception
- Toggle airplane mode on and off to refresh your connection
- Restart your device to re-establish network registration
Sometimes, simply rebooting your phone resolves temporary carrier-related glitches.
4. Restart Your Phone Regularly
Phones that run continuously for days may experience background service lags, including SMS reception failures. A full restart clears memory and resets communication modules.
Try this:
- Power off your phone completely
- Wait 30 seconds
- Turn it back on
- Wait for full signal restoration before requesting a new code
This small step resolves many unexplained technical hiccups.
5. Switch SIM Cards on Dual-SIM Devices
Dual-SIM phones sometimes misroute incoming messages. If you have two numbers active:
- Go to your phone settings
- Set the primary SIM for SMS/messages to the one linked with OKX
- Alternatively, physically swap SIM positions and test again
Ensuring the correct SIM handles messaging traffic can fix silent delivery failures.
6. Clear Your Message Inbox
Some older Android devices stop receiving new SMS when the inbox reaches capacity. Delete old messages or enable auto-delete for messages older than 30 days.
Pro tip: Archive or back up important messages before clearing.
7. Disable SMS Blocking and Filtering Apps
Security apps, anti-spam tools, or built-in phone features may mistakenly classify OKX messages as spam. To check:
- Open your default messaging app
- Navigate to Spam, Blocked, or Junk folders
- Review recent entries for any OKX-related messages
- Whitelist +86 10 8343XXXX (OKX official sender ID) if possible
Also, temporarily disable third-party SMS blockers during login attempts.
👉 Secure your account access now with reliable verification methods.
8. Avoid Frequent Request Attempts
Repeatedly clicking “Resend Code” within minutes can trigger temporary blocks due to system abuse detection.
Best practice:
- Wait at least 2 minutes between attempts
- After 3 failed tries, pause for 1–2 hours
- Use alternative methods (email or voice) instead of resending SMS
This prevents rate-limiting and improves success rates.
9. Reset Your Phone Number via Identity Verification
If none of the above work, consider resetting your registered phone number:
You’ll need:
- Access to your verified email address
- A valid government-issued ID (passport, driver’s license)
- A short video confirming identity (may be required)
Steps:
- Log in to OKX (use email or recovery options)
- Go to Security Settings > Phone Number > Change
- Follow prompts to verify identity
- Enter new number and confirm
⚠️ Note: After successful reset, withdrawal functions are locked for 24 hours for security reasons.
10. Contact OKX Support Directly
When all else fails, submit a support ticket:
- Visit the OKX Help Center
- Select Account & Verification > SMS Issues
Provide:
- Account email/phone
- Screenshot of failed attempts (if available)
- Description of steps already tried
Support typically responds within hours, especially for high-priority access issues.
Frequently Asked Questions (FAQ)
Q: Why am I not getting the OKX verification code even though my phone has signal?
A: Even with good signal, carrier filtering, app permissions, or temporary system delays can block SMS. Try voice call verification or check your email as immediate alternatives.
Q: Does OKX send verification codes internationally?
A: Yes, OKX supports global SMS delivery. However, some countries may have restrictions due to local telecom policies. In such cases, using voice verification or updating to a local number helps.
Q: How long does it take to reset my phone number on OKX?
A: The review process usually takes under one hour. Ensure your documents are clear and valid to avoid delays.
Q: Can I use the same email and phone number on multiple OKX accounts?
