The default information of Android phone cannot be used. I downloaded the hello message, and then I couldn't receive the verification code. Others can be received. What happened?

There are mainly the following points: the verification code is blocked. Check the spam message interception in the security software to see if it is intercepted. If it is intercepted, it will be recovered. Download antivirus software, update virus database, and kill SMS. The mobile phone is full of bad network conditions and poor signal, and the mobile phone can't receive the signal. Maybe you have applied to the operator to block the SMS number, or blacklisted it, the phone is in arrears or stopped to restore the factory settings or tried to uninstall the hello SMS. If you still can't receive it in the end, it is recommended to unplug the SIM and try another mobile phone.
