Why can't the social security card receive the SMS to remind Apple to receive the verification code?

Confirm whether it is a bound local phone number. If so, it's the phone itself. You can change your phone.

I haven't received SMS verification code for a long time, or it may be that the number of times I get it exceeds the limit, I don't support mobile phone service, mobile phone security software intercepts (for smart phone users who have installed security software), and the SMS gateway is congested or abnormal. You can check it once.
