Unprotected mode Why can't the security center receive SMS?

Unable to receive SMS verification code, which may be caused by the following reasons:

First, you get more than the limit. If it is over, please try again tomorrow.

Second, the mobile phone business is not supported. Mobile phone numbers in more than 0/00 countries around the world are now supported, and some numbers will be restricted by mobile phone service operators. I suggest you try to change another mobile phone number.

Third, mobile phone security software interception (for smart phone users who have installed security software). Turn on the mobile phone security software, temporarily turn off the interception function, and then try to get the verification code again.

Fourth, the SMS gateway is congested or abnormal. When the SMS gateway is congested or abnormal, the sent SMS will be delayed or lost. It is recommended to try to obtain it later.

5. Use a mobile phone abroad or use an overseas mobile phone. Affected by the business of mobile phone service operators, mobile phones cannot receive verification codes when used overseas or when used overseas. It is recommended to replace the mobile phone as much as possible.

Sixth, people around you can use it normally, but they can't get it. Maybe it's the phone itself. It is recommended to change the mobile phone card to someone else's mobile phone and try again.
