I've had Straight Talk / AT&T for a while. I've noticed recently when 120 miles from home, I had no data. BUT family with an AT&T contract phone had 4G! As I've been looking around, I see Straight Talk and AT&T had a falling out and ST no longer offers AT&T sims. It seems that ST is now a 2nd class citizen for AT&T. I've even noticed my data rates and connectivity has dropped when in the Dallas, Plano & Frisco area. Anyone else seeing this?
