The present invention proposes method for routing a message from an origin (1, 1A, 1B) to a destination (5), said destination being adapted to have a subscription to plural networks (GPRS-NW, GSM-NW) adapted to transmit messages, said method comprising the steps of: determining (S21), whether said destination (5) has a multiple network subscription; selecting (S24) a route for said message through said multiple networks (GSM-NW, GPRS-NW), if said destination (5) has a multiple network subscription; and transferring (S25) said message from said origin to said destination via said selected route, wherein said selected route is selected dependent on a value of a route indicator (ROUT_IND). Also, the present invention indicates a corresponding message routing device. Consequently, according to the present invention, a more efficient delivery of messages is achieved, since unsuccessful attempts for message delivery can be significantly reduced. Also, the resources of the network can be saved with the present invention being implented, since the best route for a message can be chosen and selected according to the prevailing situation at the destination, i.e. the subscriber terminal. Thus, the route indicator parameter (on the SMSC-SMS-GMSC interface) can optimize the routing of messages such as SMS messages, can cause an increased success rate for message delivery using the first route at a first attempt, and in consequence, reduces the load in network control devices such as MSC's and on corresponding interfaces.
