Why can't I receive the verification code sent by Apple's mobile phone?

Why can't Apple's mobile phone receive the verification code for downloading things?

I haven't received the SMS verification code for a long time, which may be caused by the following reasons:

First, the number of acquisitions exceeds the limit.

Solution: Only 20 verification codes can be obtained every day. If you have exceeded the quantity today, please try again tomorrow.

Second, the mobile phone business does not support it.

Solution: At present, it has supported all market segments of the three major mobile operators in China.

But Tibet, Xinjiang, Hong Kong, Macao and Taiwan and overseas mobile phone numbers

It will be restricted by mobile phone service operators, so it cannot handle mobile telephone service. I suggest you try another mobile phone number.

Note: Some users transfer their numbers to the Internet.

Due to the change of data interface, you can't receive short messages from third parties for the time being. Please call Netease customer service hotline for consultation.

Reason 3: Mobile phone security software interception (for smartphone users who have installed security software)

Solution: Open the mobile phone security software, temporarily turn off the interception function, and then try to get the verification code again.

Reason 4: SMS gateway is congested or abnormal.

Solution: When the SMS gateway is congested or abnormal, the sent SMS will be delayed or lost. I suggest you try it again after a while.

Reason 5: Mobile phones are used abroad or overseas mobile phones are used.

Solution: Due to the influence of mobile phone service provider's business, the mobile phone cannot receive the verification code when it is used abroad or used abroad. It is recommended to replace the mobile phone as much as possible.

Reason 6: People around you can use it normally, but they can't get it themselves.

Solution: It may be the phone itself. It is suggested to change the mobile phone card to someone else's mobile phone and try again.

In the settings, select the password settings for itunes store and APPStore, and turn off the passwords required for free download.
