Hi bg_livelaughluv. My name is Straight Talk Charisse and I will be addressing your question. As long as the phone is an AT&T GSM phone, T-Mobile GSM phone, or an UNLOCKED domestic GSM phone, then it should work. To view more about the BYOP (Bring Your Own Phone) program, you can visit this site www.straighttalkSIM.com
or we can assist you here directly. Thanks.
