Sony Ericsson launches two new dual function USB modems

Sony Ericsson unveils the MD400 and MD400g – 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 brought together in a stylish and attractive design. Apart from an in-built antenna, an innovative additional swivel antenna optimizes the performance when in use. When closed, it covers and protects the retractable USB connector. The MD400g also has an in-built GPS receiver which automatically shows the user’s current location.

For people on the move keeping in touch via the internet with colleagues, clients, friends and family is a necessity. Now Sony Ericsson gives users the speed they need in a stylish way with its two new modems complete with HSPA technology. Users can receive 7.2Mb/s in download and up to 2.0Mb/s in upload speeds. This means that sending attachments via email such as images or video content can be sent up to five times faster than before.

“The MD400 and MD400g are high performance and stylish devices that enable you to have all your essentials at hand even when you are out of reach from broadband at home or in the office. The USBs are simple, quick to install and the multiple technologies guarantee internet access every time,” said Johan Tysklind, marketing director mobile computing at Sony Ericsson. “The combined M2 Memory Stick Micro™ and the microSD™ slot really makes these products stand out from the crowd and the MD400g even includes a GPS receiver.”
