Can my phone affected by malware through mobile phone signal?

My phone is newly bought. Can a hacker actually scans the mobile phone signal around me, detect it, and put virus/malware into my phone THROUGH the mobile phone signal of my mobile service provider? Assuming the hacker doesn't know my number. I turn off bluetooth and no wifi connection. Is is possible to affect by malware through mobile phone signal, and also the radio frequency signal?? HELP.
