Why does Apple's mobile phone send a verification code when downloading something, but I still can't receive it?

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 exceeded the limit.

Solution: You can only get the verification code 20 times a day. If you have exceeded this number today, please try again tomorrow.

Second, the mobile phone business does not support it.

Solution: At present, all segments of the three major domestic mobile operators have been supported.

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

Will be limited by the business of mobile phone service operators, unable to handle mobile phone business. I suggest you try another mobile phone number.

Note: Some users transfer their numbers to the Internet.

Due to the change of data interface, it is temporarily impossible to receive short messages from third parties. 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 again later.

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.

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