Who called from 2132575233

call at 9:25 am, caller id said wireless caller, did not pick up, they left no message

I received a call at work on my cell phone from this number. No message left.  I was worried until I read other posts. How do I block a number?

Hubby answered my cell, and the caller said I won a trip to Bermuda. He hung up, and I will lock.

I never answered it. Good thing I didn't.
