How to get internet service on an ipod touch like an iphone?

So i have a wireless router at home and use it for my ipod touch but how can i get internet like an iphone. Like when i go in the car and you don't need wi-fi like an iphone. So is there something i can do it like an iphone.

For example, some people get these wi-fi thingies for their laptop but the don't need wi-fi, just the card thing that helps you stay connected.How to get internet service on an ipod touch like an iphone?Like, so, no. You can't. Like, because, the iPhone uses 3G. The iPod Touch can't do that.



For example: you can't.





You can buy a Wi-Fi router from Verizon to put in your car, but they're really expensive...not worth it...
