AITAH for not buying my daughter a phone?

My daughter is 14 and has no phone at all. I told her if she wants to text people she can use my phone, she never adds their numbers.

She used to beg for one when she was 9-11 then stopped. I don't think she needs one because she doesn't go anywhere, I would have to monitor it, (I've caught her doing inappropriate things online before) and it's very expensive. 90-100 dollars a month would be a lot of money for me. Her siblings never had phones until they were adults, I didn't have one until I was in my late 20s.

AITAH?

Edit: I accept that I am an asshole for what I mentioned on yesterdays post. I made this post to ask weather or not I'm an asshole for not getting her a phone, I have reasons for that I didn't mention on yesterdays post. I will be trying to help my daughter build a social life from now on.
