In a wireless communication device having a first and a second radio access interface for respectively communicating with a first and a second access network, a method for retrieving content comprises receiving a request for retrieval of content from a remote server and retrieving a first part of the requested content over a first radio access technology connection. When the retrieval of the first part is determined not to meet a required QoS threshold, the second radio access interface is activated. A next part of the requested content to be retrieved is divided into a first portion for retrieval over the first radio access technology connection and a second portion for retrieval over a second radio access technology connection such that retrieval of the first and second portions are estimated to meet the required QoS threshold, and are retrieved over the first and second radio access technology connections, respectively.
