How to get AT&T Samsung Galaxy Mini to work with my Straight Talk SIM card?

[AC Question]

I currently have a straight talk LG phone that I have broken the display on. A friend gave me a Samsung Galaxy S4 Mini to use instead. How do I get the Mini to recognize my straight talk SIM card?? Thank you.

Assuming it's an AT&T Straight Talk SIM, just put the SIM card in. If it's a SIM card for a different carrier (Straight Talk is the network operator, the carriers are AT&T, Sprint, TMobile and Verizon), you'll need a Straight Talk AT&T micro-SIM - contact Staight Talk tech support.
