How much is the iphone 4 bill every month for verizon wireless or sprint?

I currently have a Metro PCS phone & they're phone service suck so for my birthday my mom is getting me a iPhone but i'm unsure which phone company I would like to go to, but I know that I would like to go to AT&T or either Verizon Wireless. I text alot & I use the web alot but I don't talk on the phone that much. I'll be 16 in August & I was also wondering do my mom have to always pay my phone bill since it's in her name or can I do it sometimes?

Sprint. -90.
Verizon- 90-140-160

  • Why does my bill come up at 190 a month in sprint? From what I remember my plan was suppose to be 80 a month what the heck is going on did I do something wrong? I got this phone a year ago it's a two year contact iPhone 5 I was a new customer.
  • What will my monthly verizon wireless bill be? With the iphone 5c if i chose unlimited + 2gb share everything plan it says $60 per month and $40 for the line. Does that mean my bill will be $100 a month or are there other factors in the bill?
  • Verizon Wireless vs Cricket Wireless? On Friday I'm going to get the iPhone 5 and I have an option between those two carriers. So which is better. Please give information about both.
  • Unlimited talk and text but still high bill (Verizon Wireless)? So I have an iPhone 4 by Verizon with unlimited talk and text. When I first bought this phone I was paying 103.00 for a while, then it went up to 104, 111 and kept getting higher. So a few days ago i receive my bill in the mail and it said 160! What the heck. I'm not buying any apps, I get them all for free, my data is extremely low… What is going on? Is there any way I can make my bill go down to it's original price? I'd much appreciate the help
