What should I do if the SMS verification code is not received?

If you don't receive the SMS verification code, you can check the settings to ensure the normal network connection, adjust the SMS application settings, contact the operator, deal with spam filtering, and use other verification methods.

1, check the settings.

There may be something wrong with one of the settings, which makes the mobile phone unable to receive emails normally. These situations are usually caused by personalization or modification of some system settings. Make sure the volume of the mobile phone is set normally, and switch to normal mode. Check the block or block list and delete the sending number of verification code SMS from the list. Turn off the flight mode and ensure that the mobile phone is within the normal signal range.

2. Make sure the network connection is normal.

Move to the area with strong signal and try to receive the verification code message again. Check the data connection settings of the mobile phone to ensure that the mobile phone is in normal working condition. Abnormal mail network segments or carrier mass sending platforms or traffic jams can also lead to difficulties in receiving mobile mail. In these cases, delays usually occur. It is suggested to wait for a while and resend the verification code of the mobile phone mailbox.

3. Adjust the SMS application settings.

Check whether the mobile phone is set to intercept emails, and check whether the intercepted emails are received. Generally, if the mobile phone is equipped with interception software such as email firewall or mobile phone security guard, it will have an impact. If closed, cancel. Clean up the SMS storage space and delete some old SMS to make room. Disable or uninstall third-party SMS applications that may interfere with the reception of verification code SMS.

Step 4 contact the operator

If the mobile phone still can't receive the SMS verification code, it may be the operator's problem. Contact the operator's customer service to find out whether there are any shielding rules for verification code SMS, and request to remove the relevant shielding.

5, to deal with spam filtering.

Some mobile phones have SMS interception function, which may misjudge the verification code SMS as spam SMS. Please check the SMS interception settings to ensure that SMS with verification code is not intercepted by mistake. Sometimes, SMS verification code may be blocked due to unintentional blacklist operation. Check the spam message filtering settings of the mobile phone, and add the sending number or keywords of the verification code message to the white list.

6. Use other authentication methods

Some applications support a variety of verification methods, besides SMS verification code, you can also choose voice verification code, email verification and other methods. You can try other verification methods to ensure that the verification is completed successfully.
