Why does Apple 8 download something and send it to the mobile phone for verification? But the mobile phone has never received the verification code.

Can't receive the verification code when authenticating the mobile phone?

This may be due to the following conditions:

1, SMS storage is full. The short message storage capacity of mobile phone is limited. If you don't clear the received SMS in time, you won't receive the follow-up SMS. It is recommended to delete the message and try again.

2. If your mobile phone is not turned on for a long time or in a place with poor signal for a long time, the short message sent to you will be invalid because it expires. Suggest to try another place; (The validity time of the verification string is: 20 minutes)

3. It is related to the local gateway. Due to the large number of local short messages in some time periods and the busy short message center, short messages may be affected, delayed or lost. I suggest you try again at another time later.

4. It is related to the SMS platform of the operator. There are also individual failures (inconsistent sorting), such as: the mobile phone number belongs to the newly opened number segment, and it is not registered in Tencent Information Center, so it is impossible to receive SP short messages. You can contact our customer service center in time and leave your corresponding mobile phone number, mobile phone location, occurrence time and specific situation. We will find out the reason as soon as possible and help you solve it in time.
