How can I convince my mom to let me buy something with my own money?

-Ok. So I have been earning my own money recently to buy something for myself for my birthday coming up. I want an Android phone to replace this lame pay as you go cell phone that i got a couple years ago that my mom won't even refill with money, and won't let me refill it myself with my money either. I have enough money to buy the android phone myself, and that I'm trying to be responsible by using my own money. But she said "no" "because I don't need it and she's pretty sure I'm not going to pay the monthly fees" I tried everything! more chores, helping, but it won't work! And the lamest part of it all is that my brother earns his own money too and he can just buy a weird 100 dollar lego set. I don't get it. Does anyone know what else I can do?tell I wanna be independent on spending my own money. and tell her my phone is getting too old and I wanna replace it(even if it's completely new!) so I extremely need this phone and it's not useless.I agree with your mom. The monthly fees are very high and I don't think you'll be able to continue to pay them month after month for the next three or so years either. Mom doesn't want or need that added expense.



Believe it or not, people get by without cell phones. Lots of people.
May I ask how old you are? My answer would be different depending on whether you're 8 (yes, you probably are too young) or 18.
I kinda had something like this when i bought my phone i got the evo from sprint. If i were you id just tell your mom that your gonna make an educated purchase (it sounds good with fancy words) and that she doesn't have to worry about any of the money. Also use the weird 100 dollar lego set thing against her and say if he can have that why cant i have this. And if she says no just keep bringing it up. after a while shes gonna have to let you have it eventually.
