I bought a Mi9.
When I insert the sim from my other phone it stops working:
it turns black with the fingerprint and 3 android buttons at bottom (square, circle, triangle)

If I switch it off, then insert the sim, then reboot...
it boots after several minutes and the same problem.
Once it has displayed 3 options : reboot + factory settings + another option I don't remember

What should I do ?
