Daughter wants a new phone

I ended up in the principals office with my daughter last week because she was being accused of cyber bullying. I did defend her to the guidance counselor but when we got home I asked for her phone. I told her I needed to look through it to see if she's cyber bullying. Instead of giving it to me she threw it in the water my son put in the sink to do the dishes. So that happened and that confirmed she had actually been cyber bullying which I made her apologize to this girl the next day.

Now she's saying she needs a new phone and I said if she wanted a phone she shouldn't have destroyed the $900 phone I had already gotten her. I understand the importance of having a phone on you especially a teenage girl but the most im willing to do is the cheapest drug dealer phone with no Internet She's upset about it because she thinks she needs a smartphone. I feel that she destroyed her phone. She doesn't get a shiny new smart phone. She obviously can't be trusted on social media

*** The only reason I'm willing to do burner phone is because on Fridays she walks home from school because she had tutoring and while it's not far she will be walking at night.

**** IDK why some of you are acting like I'm not taking this seriously just because I want her to have a burner phone that she can do nothing besides call. In this day and age a phone is a necessity. Especially if she's 15 walking home at night by herself. I think it would be irresponsible of me to not make sure she has a way to communicate if she a teenage girl is walking home at night alone. I'm going to hold her accountable but potentially endangering her is not a fair punishment. My daughter is a victim of S.A. already and I don't think there's anything wrong with giving her a burner phone for when she walks home at NIGHT alone.
