New Iphone. Should I buy it?

Back-round: I'm a college student who currently has an Iphone 7+. I transfer out to university this upcoming fall semester (I've been at community college) meaning I'll be extra broke and won't be able to afford any sort of phone upgrade for probably the next 2+ years. I have the money now, should i go for it?

Also, I like the quality of apples cameras/software compatibility too much to go back to an android phone.

How to get a job at age 13? - 1

I want to buy an iPhone 7, my mum said if I wanted one I had to buy it myself otherwise just stick to the one I have now. That's fine by me, I know her money doesn't grow on trees, only how do I get a job at age 13? I'm seriously considering this. I'm from the UK if that helps.

Thanks in advance.

What phones do 13-year-olds have?

Mine has the Samsung Galaxy S5 I got her in July. When she first got it she said this is pretty old and all her friends have iPhone 6, 6s or 7. I told her we're on a budget and to be gratful for what she has, she accepted this and hasn't complained since. Do you know a 13 year old? This can be a daughter, son, cousin, neice, nephew, friend, etc. What type of phone do they have? I'm thinking of getting mine one for Christmas.
She needs a phone because she often goes out with her friends without me, she needs to be able to call or text me so I know where she is. She also uses it for homework sometimes and likes to play games, text her friends, etc. She has a parental lock so I know what she's doing and how much screen time she's having too.
