The aircraft software cannot receive the verification code.

Does the subject want to ask, "What is the reason why the aircraft software can't receive the verification code?" Network instability, wrong mobile phone number, expired verification code, mobile phone short message filtering.

1. Network instability: The network signal needs to be unblocked when sending the verification code. When the network is unstable, the verification code will be late or even not received.

2. Wrong mobile phone number: the entered mobile phone number is wrong, and the verification code will be sent to the wrong number.

3. The verification code has expired: the validity of the verification code is only a few minutes. If you don't enter the verification code in time after receiving it and wait too long, the verification code will be invalid.

4. SMS filtering: The mobile phone will automatically identify the SMS with the verification code as spam SMS and advertising SMS, resulting in the failure to receive the verification code in time.
