A system for delayed message delivery can include an IP Multimedia Subsystem (IMS) network that is in communication with at least one of a first user equipment and a second user equipment, and a message application server. The message application server can be configured to receive a message sent from the first user equipment, store the message temporarily in accordance with a time parameter, and send the message to a gateway when the time parameter is satisfied. The gateway can be configured to receive a message formatted in accordance with a first protocol used by the IMS network and convert the message into a format in accordance with a second protocol used by a message center. The message center can be configured to receive the message formatted in accordance with the second protocol and forward the message to the second user equipment. Other systems for delayed message delivery and corresponding methods are disclosed.
