Start Screen Stuck

Hello

I just open a new Zebra TC56 Device and I got the screen, its showing Insert Sim Card or Skip, and as well, the screen is kinda blinking, as well as when I click on skip it just blinks and stays on skip, sometimes it go to next page and then comes back to skip and it keeps on blinking.

I tried to format by clicking + and ptt and power but no use only the - and ptt and power work but it shows sd card and adb, any solution?

Thanks
