How does PHS receive SMS reminders?

Hey hey, give a professional explanation:

From the process point of view, the order of mobile SMS to PHS is:

Mobile phone-> SMS Center-> SMS gateway->; Telecom SMS gateway->; Telecom short message center-> PHS mobile phone.

The other party's short message can't reach you here, and there may be something wrong with any link.

If he can send it to other PHS, then it is ok to go to the mobile SMS gateway.

If the telecom short message gateway is lost, it may be that the telecom or mobile gateway has not routed your number segment.

If the short message gateway forwards it to the telecom short message center normally, it depends on the log whether it can be sent or not. I won't go into details. There are many reasons for the error, and it is likely to be related to roaming if we want to analyze the specific problems. Because PHS didn't support roaming at first, it just added the concept of mobile roaming. Today, roaming between devices from different manufacturers is still more or less problematic.

It is suggested that both parties call customer service to inquire. It's best to ask the technicians of Netcom to follow the message on the gateway, and you can ask the other party to send two short messages to try. This will make the problem clear at a glance.
