The deal means that Siemens is sponsoring the evening drive-time show presented by Richard Kaufman.
The campaign gives listeners the opportunity to take part in interactive competitions using the Siemens picture messaging phone, the S55.
There will also be competitions where listeners can win the Siemens A50.
Charlotte Mitchell, Siemens mobile events and sponsorship manager, said: "Siemens mobile is the number two manufacturer in the UK and has ambitious growth plans. We are currently a sponsor of many UK premiership clubs, including Chelsea and Liverpool, and so the sponsorship of TalkSPORT is a perfect medium to engage sports fans."
