Beijing unified reservation registration SMS verification code is always very slow, what should I do?

I don't know. At 9: 30, the advertisements on the SMS channel are crowded. If the hospital uses ordinary channels, it will be affected. You can check whether it belongs to mobile, Unicom or other operators according to the first few numbers of the received SMS, and then receive the SMS verification code with the corresponding mobile phone. In addition, make sure the signal in your area is good. Good luck. The SMS service codes of China Mobile will be uniformly adjusted to 10657 and 10658. The short message service code of China Unicom will be uniformly adjusted to 10655. The short message service code of China Telecom will be uniformly adjusted to 10659. The short message service code of China Netcom will be uniformly adjusted to 10656. The SMS service code of China Tietong will be adjusted to 65438.
