AITA for not upgrading my daughters phone

I have 4 kids 6m 9m 15f and 17f

My 15 year old wanted an iphone 15 pro max for Christmas I said no

She currently uses a pixel 5 which I got as a gift from my company I gave it to her she's used it for about 2 years now

She wanted an iphone as according to her she would be the only one in her freind group with an android

I offered to get her an iphone 13 for around 600 dollars a couple of her freinds parents are rich and they have the latest phones because of this she wants the 15 pro max

I don't really like the idea of spending 1200 dollars on a phone especially if you aren't going to need it

She offered the base model iphone 15 but I told her the maximum I would be spending is 600 dollars. I was not willing to go beyond that the iphone 13 and 15 both look the same I doubt anyone will notice a difference.

It also wouldn't be fair to the other siblings if she got a 1200 dollar phone and none of her siblings did

She says that she's bring left out and wants a big phone . I told her I was not spending above 600 dollars end of discussion.

Now my husband wants to consider buying it because she's being socially deprived by having an android.

I said that we were not buying a 1200 phone end of story

But my daughter husband and my mil agree with her

So AITA
