Well sucky for me, I don't have a cellphone anymore.
I always had a cell phone since I was 11...then a year ago, I kind of fukced up...bad...so she took is away. And I haven't gotten one since...hopefully my birthday though!
But when I had one, I couldn't text too much(this was before she got unlimited texting on the plan) and I just had to make sure I watched myt ime talking on the phone if it wasn't free. (it was free after 9pm and on weekends)
