Alongside a raft of new handsets, Sony Ericsson has released two dual-function HSPA USB modems, the MD400 and the MD400g, delivering download speeds of 7.2Mb/s and upload speeds of up to 2.0Mb/s.
The devices are the first HSPA USB modems of their kind from Sony Ericsson, not only providing high speed broadband but also a combined M2 Memory Stick Micro and a microSD slot. Both feature an in-built antenna, with an additional swivel antenna to optimize performance. When closed, it covers and protects the retractable USB connector. The MD400g also has an in-built GPS receiver which automatically shows the users current location.
