How to set up net10 to iphone 4?

I have a unlocked iphone4 it was on at&t. I want to set it up for net10. I have a sim card that is not registerd yet because i want to know it is going to before i buy the 50$ plan. What are my next step to getting it to work on my iphone. I got the sim in my phone it says no service

I Just recently did the same thing. It's saying No service because your sim card is not registered yet. Once registered, you will be able to make calls and do all that cool stuff.

You need to change the APN settings. You can find out how to change the APN settings on the Net10 web page.
