An arrangement for a wireless communication device is disclosed. The arrangement is adapted to set up an application connection between an application of an application layer of the device and a remote server. The device comprises a modem subsystem (comprising the application layer, a remote socket client and a remote socket API between the application layer and the remote socket client), an application processor (comprising a remote socket server and an IP stack, wherein the application processor is associated with a wireless communication access unit and the IP stack is adapted to connect to a communication network using the access unit), and a remote socket protocol communication channel between the remote socket client and the remote socket server. The application is adapted to send an application connection setup request to the remote socket client via the remote socket API. The remote socket client, the remote socket server and the remote socket protocol communication channel are collectively adapted to use a remote socket protocol to set up a remote socket connection between the remote socket client and the remote server via the remote socket server and via the IP stack, using the remote socket protocol communication channel and the wireless communication access unit, and to establish the application connection based on the remote socket connection. The remote socket client is further adapted to (in response to the application connection being established) send an application connection setup response to the application via the remote socket API.
