How many days will MMS be kept if it is not accepted by others?

The short color center will save unsuccessful content for a short time, generally 48 hours for SMS and 24 hours for MMS; That is to say, if after sending, the receiver can't receive it because it is turned off or unable to connect, the short lottery center will temporarily save it, and after the receiver's mobile phone returns to normal state within the validity period, it can normally receive the content sent by the center again. However, if the retention period is exceeded and the recipient's mobile phone has not been restored, the SMS center will clear this content and stop the appointment!

I hope I can help you!
