Who called from 3102892348

that phone number keeps calling me and hanging up without saying anything.. i blocked the number

Same here, get 3-4 calls a day from it.  No response when answering and no message left.

Calls 3-4 times daily- no one on line when I answer. Very annoying

Received 3-5 calls a day-write number down-call back from a different number, the phone rings, rings and rings no one answers. Call the next day- no ring tone and it hangs by itself..

Blocked.  Tries calling cell 2 to 3 times a day, every day.  Of course, no VM.
