How does Huawei mobile phone know SMS verification code?

Generally, Huawei mobile phones can receive SMS verification codes normally. If your Huawei mobile phone fails to receive SMS verification code, I suggest you restart your mobile phone first, and then try to see if you can receive SMS verification code. If not, you can call the telecom operator and ask if the SMS receiving function of this mobile phone number is normal. If so, you can contact Huawei customer service to explain the situation.
