What is the reason for the delay in receiving verification code by mobile phone?

What is the delay in receiving verification code by mobile phone? It may be that there is something wrong with the SMS center of the operator and it has not been sent out. Of course, it may also be that the cell phone signal is not good, it is not registered in HLR, and the SMS gateway can't find a route to send it to the cell phone. It depends on the transmission speed and response speed of the base station. Usually, the communication base stations of telecom operators have a certain amount of data buffer. Once this value is exceeded, users will be affected by online call delay. The delay in receiving SMS is also related to the network of the mobile phone itself.
