I had a Pantech Reveal for about a week when I was 10, before I lost it at school like an idiot. Then from June 2013 to November 2014, an iPhone 4. After that, an iPhone 5C. Now a 6S, which I've had since October. I have no shame in it.
Yes I do have a phone, I got mine in 7th grade when I was 12. Didn't really need one until I was like a freshman in high school though lol, but it really depends on the person as to when you should get a cell phone I feel like.
