Sue Barker explains how you can vote for the 2012 BBC Sports Personality of the Year, which takes place on Sunday at London's ExCel Arena.
The way to vote from a mobile is slightly different this year, you will be given a short number that you need to call, not text.
You will need to call the short number given out during the show, and add the two digits of the sports star you would like to vote for.
Using this number from your mobile will mean your call will cost you just 15p.
