AITA for giving my daughter a different phone than her friends?

My daughter is 13. Her parents are divorced but they are still friends. We both recently bought her and her brother new phones. I bought him and her identical phones but her mother thought that she wanted a more expensive phone. <br><br>She has one of each phone now and whenever she is at her moms house, she has to use that one and at my house, she uses the one I bought her. <br><br>Her friends at school have the more expensive phone and they have been teasing her that when she is at my house, she is “that poor girl who can’t afford an iPhone” (it’s actually something else but doesn’t matter). <br><br>I told her that she could just use her mom’s phone at my house and keep it charged but she said that her mom will want her to stay at her house if that’s the case. <br><br>She asked me to replace the phone I bought her with the same one her mom bought her and I declined. First of all it is just a phone and she has everything she needs. <br><br>Second I see this as her mom trying to one up me and make it seem like she is the better parent. She has hinted at this which I think is completely ridiculous. <br><br>She has been asking multiple times and said that she hates this phone and that it’s so basic. I feel like I’ve done nothing wrong and she has said she hates both phones and they’re basic but she prefers her moms phone. <br><br>But I don’t want her to feel left out at school or think I don’t want to help her fit in.
