i just dont know how they got my cell if i dont use that number for anything other than family...  (i wonder if tmobile sells my info)
mfkrs P.O.S. all of them!!!

several calls, no answer and they leave no voicemail. I blocked number with iphone.

Same here this number continues to call me every time I answer it hangs up.

They just called again how do you block the phone using the Android phone?

For Andriod, save the number on your phone. Click on the contact. There should be a way you can add the number to a reject list. I do it all the time.
