My 15 year old daughter wants a phone, how do I stop her complaining?

My 15 year old daughter has an iPhone, but she wants to make calls on it so she can talk to her friends. I think it's great that she wants to talk to her friends but she can't pay for a phone because she's not old enough to get a job. I give her $5 a week for her allowance, so that's $20 a month. She can pay for a phone, but she complains that if she paid for her phone every month then she wouldn't be able to spend her money since it costs at least $20 a month to make calls on a phone. I told her she can work in the summer to pay for her phone, but she says that won't be enough money because she'd only be working in the summer and not all the time to keep up with paying for her phone.

IPhone 6s vibrate problem?

My iPhone 6s seems to slightly vibrate when I rub the back with my hand? Any ideas what this could be?

Why does my car no longer recognize all my iphones music?

All of a sudden my car (2016 Chrysler 200) no longer recognizes all of the songs I have on my iphones music setting.

The display now ways UNKNOWN ARTIST when attached and it only plays the alphabetically first song on my music list… And then repeats it.

When I try to turn off the repeat song option using the iphone the button turns off for a second and then returns to repeat mode without me pressing it again.

It almost feels like my car no longer recognizes all of my songs and only thinks it is playing one enormous song (my whole collection)

This only started happening recently and it occurs with all cords that i've tried.

Anyone seen this before?
