2 . The method of claim 1 , further comprising:

if a TCP socket cannot be opened, opening an SMS channel with the mobile device;

sending an SMS message to the mobile device;

receiving, from the mobile device, a request for data transfer;

retrieving, from the storage medium, one or more messages to be delivered to the mobile device; and

sending the data message to the mobile device over the SMS channel.

3 . The method of claim 1 , wherein the data message comprises on or more of the following:

a text message;

an instant message; and

a chat message.

4 . The method of claim 1 , wherein sending to the mobile device one or more instructions for activating the mobile device comprises:

7 . A method of conserving client resources associated with a mobile device, the method comprising:

receiving a data message for an intended subscriber of a mobile solution provider, wherein the intended subscriber is associated with the mobile device;

storing the data message in a computer-readable storage medium;

sending information to a push server, wherein the information comprises a session identification associated with the mobile device and an indication that a refresh is needed;

receiving, from the mobile device, a request for data transfer; and

sending the data message to the mobile device.

8 . The method of claim 7 , wherein receiving a data message comprises receiving one or more of the following:

10 . The method of claim 9 , wherein sending an acknowledgement message comprises sending an acknowledgement message after the data message has been sent to the mobile device.

11 . A method of restoring a chat session on a mobile device, the method comprising:

initiating a chat session between a mobile device associated with a first subscriber of a mobile solution provider and a mobile device associated with a second subscriber of the mobile solution provider;

sending a first chat identification and a second chat identification to the mobile device associated with the first subscriber, wherein the first chat identification is provided by a communication service, wherein the second chat identification is provided by the mobile solution provider;

determining whether a chat message is received after a chat session between the first subscriber and the second subscriber has ended; and
