Straight Talk APN Help?

[butterhasbeenspread]

I just upgraded from a Moto X 2013 (Unlocked) to a Moto X 2014 (Pure Edition). I'm trying to set up my Straight Talk (AT&T) APN settings with no luck. Everything worked fine on the old phone, but the new one doesn't allow data or mms. Any help would be greatly appreciated.

Update: I figured it out. I have an older sim card that only supports up to HSPA+ data, not the new 4G sim cards. I found my card that came with the sim card and the settings called for a proxy. None of the newer settings call for it.

Use the APN that came with the SIM card, or call tech support. They use different APNs for the same carrier for different SIMs.
