My internet isn't working on my iPhone 4?

I was on Telstra and my dad wanted to change me onto Kogan because i wanted to go onto a plan. And now that i'm on Kogan it doesn't have the "E" or "3G" so i can't go onto the internet. When i go onto Settings > General > Mobile Data. It has
Mobile Data (On)
Enable 3G (On) i have turned it on and off. Neither worked
Data Roaming (Off)

What do i do!

How much Internet on iPhone 5 can I use?

I'm just curious. I'm a teenager and my dad and my brother and I are on a T-mobile family plan for our three new iPhones. How much Internet do you think I'm allowed to use without going over any limits? I would ask my dad what his data plan or whatever is, but I don't want him to think I'm ungrateful for the really nice phone I have now because I used to have a flip-phone. Let me know what it usually is for the family plan, thanks.

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
