How do we BLOCK phone numbers? My 12 year old daughter's cell phone just rang for a soliciting call at 4:18 am (woke me up). The same number has called my phone roughly 17 times in the last 2 weeks. Our cells are used for text only and given only to a few friends for text only--basically private and not given out. The number that keeps calling is 1-289-680-4001.
