Who called from 3475084753

came in to my cell phone number 6:02 pm pacific coast time   I never heard my phone ring, just saw I had missed a call.  I've had at least 3 of these now and always a new number is doing this.

Rang once, no message

Phone call at 8:35 p.m. in Colorado.  Phone rang two times and then the caller hung up.

2 rings, no message. Probably scam according to everyone else.
