Why can't I get the verification code by plane?

The reason why the aircraft can't receive the verification code is as follows:

1, the number of acquisitions exceeds the limit.

Solution: You can only get the verification code three times a day. If you exceed the number of times today, please try again tomorrow.

2, mobile phone security software interception.

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

3. The 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.

4. The mobile phone is used abroad or used overseas.

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.

People around you can use it normally, but they have never received it.

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

Precautions for receiving verification code

1, pay attention to SMS interception.

In order to protect the information security of mobile phones, users will actively or passively install security software on their mobile phones. No matter what kind of security software, intercepting harassing calls and spam messages is one of the most important functions.

2. Don't disclose the verification code.

SMS verification code has entered every aspect of our life and work, and it has become very common to receive verification code messages every day. However, verification code has become the only password for various system security mechanisms. Protecting the security of authentication means ensuring the integrity of our personal information and property.
