Is there a delay for Apple to receive messages with one ID and two mobile phones?

The delay of receiving information on Apple's mobile phone is generally about 2 to 3 seconds, depending on the strength of the network signal in the area where the mobile phone is located. If there is a long delay in receiving information, it is necessary to change the location of the mobile phone and choose a location close to the mobile base station for network connection to see if the problem of long information delay can be recovered. Generally, the information delay can be reduced after changing the position.
