I need to control a Feature-phone device so we can remotely send a command to suspend operation of the device. It means, I will send a command via SMS, so the application will recognize the command and will stop normal operation of the mobil device: it means, all the incoming and outgoing services, including voice and data will be suspended. Furthermore, a subscriber will not be able to access the device to see any data stored.
Also, reactivating to normal operation of the machine, it will be done sending another command vis SMS. The phone will have to run an application to recognize the block/unblock command sent via SMS. The majority of these Chinese manufactured devices are based in CPU from vendors either Spreadtrum or Mediatek.
