My ex husband bought our 11 yr old daughter a cell phone at christmas. He recently upgraded the phone so she would get unlimited mins and texting. For the first 2 weeks of her having the new phone we would talk and text. I tried calling her last night and found out he blocked my number & her stepfathers number from her phone. I called the ex and asked him why I was blocked. He said that he pays the bill and doesnt want me contacting her on her phone. I can call her on his phone in the evening only. She is left alone at his house in the morning for a few hours while he is at work & before school starts. I have no way of reaching her to check on her. My ex's girlfriend, family, her friends & strangers are able to call/text her but me as her mother am not allowed to. Can he do this?
