Why do you need this? Are you trying to uniquely identify individual installs? If so, what will you do if your user doesn't have a SIM in his phone, or is on a tablet? Search the list. Identifying installs uniquely has been discussed before.
FYI, to see if the carrier stores the number on your SIM, go to Settings -> About Phone -> Status -> My phone Number (In ICS. Other versions may vary slightly.) If it displays unknown there, then your number is not stored on the SIM.
