A stupid rule in my house

We have this stupid rule in my house "when you become 13 you get a phone under the age of 13 in ur dreams" in my house you can have any device you want literally I have Xbox one and ps vita and playstation 3 and 4 and the new 3ds ( I love video games so much ) and a mini iPad but I don't understand why I can't get a phone I know I'm not 13 yet but all of my classmates have phones when I go out I dunno how I'm gonna call my family plus I can't take my mini ipad everywhere I go or put it in a small bag it sucks...well all what I can do is to wait I guess.💔
