Straight talk sim not working on iphone?

I had a crappy straight talk phone and just bought an iphone, so i took the sim card out and cut it into a micro sim. But when i try to put it into my iphone it just say no sim? What's the deal?

That is because you need the Straight Talk BYOD SIM card to work with the iPhone. The "regular" Straight Talk SIM cards will not work that way.

  • Why is straight talk not working in my zip code? I bought an ATT iPhone 4s and a micro sim card from straight talk that was compatible with this phone. I activated it, and it says "no service." I've heard that straight talk uses ATT towers, and they work fine in our area. So what is the problem?

When i put the sim card in the iphone a notification changes from no sim card to no service. I tried to activate the sim card using the serial number on it via straight talk website. It keeps telling that the serial number isn't recognized. I don't know if I need a new sim card or what I need to do. Can someone please help me?!
