聲紋比對，小弟不知

不過......手機是可以造假的，也不是新聞了，不要太確定手機序號絕無造假可能
(台灣，甚麼事發生，我都不會太驚訝，只會感嘆 搖頭，以台灣政黨力量，要搞這種東西也不難)

有心人還是有機會可以攔截手機通訊，並藉以複製另一支手機

以下是美國FCC(Federal Communications Commission)官方資料

What Is Cell Phone Cloning Fraud?

Every cell phone is supposed to have a unique factory-set electronic serial number (ESN) and telephone number (MIN). A cloned cell phone is one that has been reprogrammed to transmit the ESN and MIN belonging to another (legitimate) cell phone. Unscrupulous people can obtain valid ESN/MIN combinations by illegally monitoring the radio wave transmissions from the cell phones of legitimate subscribers. After cloning, both the legitimate and the fraudulent cell phones have the same ESN/MIN combination and cellular systems cannot distinguish the cloned cell phone from the legitimate one. The legitimate phone user then gets billed for the cloned phone’s calls. Call your carrier if you think you have been a victim of cloning fraud.
