A method for controlling the content of a multimedia message transmitted from a transmitting device to a receiving device (120; 140), comprising: - receiving, by a service device, a multimedia message from the transmitting device; and - determining, by the service device, whether the receiving device (120; 140) is capable of exhibiting the multimedia message to a user of the receiving device without adaptation of the multimedia message's content; the method characterised by: - using, by the service device, information in the form of a header to determine that content adaptation to the multimedia message is not permitted; - having the receiving device (120; 140) exhibit the multimedia message to the user of the receiving device if the receiving device (120; 140) is capable of exhibiting the multimedia message to the user without adaptation of the multimedia message's content; - informing, by the service device, the transmitting device that the multimedia message could not be exhibited to the user on the receiving device (120; 140) without adaptation of the multimedia message's content if the receiving device (120; 140) is not capable of exhibiting the multimedia message to the user without adaptation of the multimedia message's content; - receiving an address for a secondary device from the transmitting device; - determining whether the secondary device is capable of exhibiting the multimedia message to the user without adaptation of the multimedia message's content if the receiving device (120; 140) is not capable of exhibiting the multimedia message to the user without adaptation of the multimedia message's content; and - having the secondary device exhibit the multimedia message to the user if the secondary device is capable of exhibiting the multimedia message to the user without adaptation of the multimedia message's content. - receiving, by a service device, a multimedia message from the transmitting device; and - determining, by the service device, whether the receiving device (120; 140) is capable of exhibiting the multimedia message to a user of the receiving device without adaptation of the multimedia message's content; the method characterised by: - using, by the service device, information in the form of a header to determine that content adaptation to the multimedia message is not permitted; - having the receiving device (120; 140) exhibit the multimedia message to the user of the receiving device if the receiving device (120; 140) is capable of exhibiting the multimedia message to the user without adaptation of the multimedia message's content; - informing, by the service device, the transmitting device that the multimedia message could not be exhibited to the user on the receiving device (120; 140) without adaptation of the multimedia message's content if the receiving device (120; 140) is not capable of exhibiting the multimedia message to the user without adaptation of the multimedia message's content; - receiving an address for a secondary device from the transmitting device; - determining whether the secondary device is capable of exhibiting the multimedia message to the user without adaptation of the multimedia message's content if the receiving device (120; 140) is not capable of exhibiting the multimedia message to the user without adaptation of the multimedia message's content; and - having the secondary device exhibit the multimedia message to the user if the secondary device is capable of exhibiting the multimedia message to the user without adaptation of the multimedia message's content.
