Tracfone SIM Card work with unlocked iphone?

[rileyb76]

Guys,
I've searched the forum but haven't had any luck. I have a 3G iphone with 3.1.2 on it and a Tracfone SIM card which is active. Is there any way possible to get this SIM to work in the iphone? It has been jailbroken and unlocked with blackra1n.
Thank you in advance!

The sim might be locked to the tracfone it was activated or came with.

Thanks.
Are there any good and cheap prepaid cards at all out there with data?
