Hi,
I suggest that you open the cover for the SD-card, here you can find an OFF button which you can hold down (with the tip of a pen or a similar object) until a series of quick vibrations appear. When the phone powers off > Release the button > Remove the SIM-card and insert it again > Now power on the phone again to see if this can help.
