Can you use a Straight Talk phone with AT&T?
Yes, your SIM card will work with an AT&T compatible or unlocked GSM phone. Per the Straight Talk website; to activate your service, you will need a Straight Talk Unlimited 30-day Service Plan card or credit card. Some data services may not be available with all wireless devices.
