Who called from 212892017345

This morning I got a missed call from +25778165020. And in the evening another call from +212892017345. I wasn't wearing my glasses, so I accidentally answered it just for a second. Disconnected the moment I knew it was like Japanese language. I don't know exactly. My operator warned about such calls previously. They said these calls can extract all the details from your cell and even clone your SIM. Am I in danger? Please give an answer.
