Lost iPhone, some advice on getting a new one?

I lost my iPhone so it bugs me how I even gotta get a new one from so many things i had in the phone. But I suspended the account and then I was thinking on getting a new one from the store company. I have a plan… Would they make me pay the same amount I got the phone at first? Or more? For a replacement, cus I lost mine.

Your lost phone has nothing to do with the new phone you now have to buy. The cost will be whatever the regular retail price is. I Phones are NEVER discounted. You'll need to pay full price. Something to think about… Why waste MORE of your parents money getting a new phone when you weren't mature enough to take care of the first phone.
You are too young to have a phone.

I think you can find your phone back with Find My iPhone if it is iDevice.
You need to have set up Find My iPhone/iPad/iPod on your device prior to it getting lost or stolen. If you did, go to https://www.icloud.com/...cloud.com/ in your web browser. When you log in, Find My iPhone/iPad will immediately begin trying to locate your device.
If you have not done that, applying some anti-thief app like ilostfinder is a wise choice.

It will take pictures of the thief when she/he tries to open your device and then send those pictures to your email.

Did you install some anti-theft app like iKeymonitor which can record nearly all the activities on your iPhone? If you did, you will find it soon.

Hope it helps.
