US law enforcement is pushing smartphone makers to install a kill switch to deter theft. This is even more important in developing Asia where the value of a smartphone is even higher relative to monthly earnings. We have not had much success with IMEIs deterring theft of feature phones, despite widespread efforts in Pakistan, India and elsewhere. Hopefully, the solution to smartphone theft will be more effective: “It is totally unacceptable that we have an epidemic of crime that we believe can be eliminated if the technological fixes that we believe are available are put into place,” Mr. Schneiderman said.
