How long will it take to receive the message after the SMS is turned off?

The text message sent by the other party when it is turned off will still be sent as usual, but you can't see your text message until the other party's mobile phone is turned on.

Generally, when the other party turns off the phone after sending a short message, it will be stored in the short message center for 48 hours, and it will be received as long as it is turned on within 48 hours.

But there are also cases where it is not received. For example, when the system is too busy, you will occasionally lose text messages. Or if the other party's mobile phone stops, it won't be received, because once it stops, his (her) various businesses will be temporarily closed, so it won't be received again.

SMS can be initiated by mobile communication terminals (mobile phones), SMS platform servers of mobile network operators, and network service providers (including ICP and ISP). ) interconnected with the SMS platform of mobile operators.

With the spread of short messages from mobile phones to PHS and fixed terminals, and from digital mobile communication network to fixed telephone network, people's understanding of short messages is no longer just regarded as the "patent" of digital mobile phones. Business forms are changing, network elements are changing, and information content is rich. In this process, only two things remain unchanged:

First, the message length of short message is always less than 160 English or numeric characters or 70 Chinese characters, which is closely related to the mechanism of short message transmission based on the signaling network of communication system. The second way is to send short messages-store and forward. When the user does not receive it, the short message will not be lost and will be temporarily stored in the short message center. When the user logs on to the network again, the short message will be quickly submitted to the user's mobile phone.
