Middle grade tween girl book where a girl moves to a fancier school because of a connection her dad made at work

It was a fairly short book with a couple others in the same series. There wasn't really a plot, it was just one of those middle school slice of life type of books, kind of like in the same genre as The Cupcake Diaries or The Babysitter's Club. Here's some stuff that I remember happened in it:

• MC girl gets set up for a prank and ends up involuntarily splashing their strict science teacher with soda, due to a sort of "prank initiation" for becoming popular.
• There's the classic group of three mean popular girls that the mc initially hangs out with. One of their dads works with the mc's dad, and that girl is closest to the mc out of the three popular girls
  • That girl (the one the mc is closest two out of the three) likes a boy, but is disapproved by her other friends because they're the same height, meaning that she would be taller than him if she ever wore any sort of heel. There's a school dance later on (possibly the next book), and she goes with him, and the mc thinks they look good together, even if she is a little taller.
• There's another side character who's sporty, has short hair, and rides a skateboard, and becomes the mc's main friend. She used to be best friends with one of the mean popular girls (the leader). During a sleepover in the past, the mean girl cut off all of the sporty girl's long hair as a prank, which is why they're no longer friends.
• MC gets a cell phone thanks to one of the popular girls with a pre-paid payment plan, her older brother complains about it and their mom said that if he can find a way to get a phone without needing their parents to pay for it then he could get one too
