Hi everyone, I was hoping someone could help me figure this out. I have an AT&T LTE sim that has data and voice on it. This sim works fine in my AT&T iPad 3 - LTE works fine on the iPad 3 too. The sim also works fine with LTE in my unlocked iPhone 5. However, when I put it inside my AT&T iPad Mini, it doesnt work at all. I used the online APN changer and switched the APN settings to AT&T HSPA+. That made the SIM work in the iPad Mini, but with 4G only. I have tried changing the APN settings several times over, but I still can't get LTE on the iPad Mini with the SIM. So I'm confused - shouldnt the AT&T iPad Mini be unlocked and work just like the bigger AT&T iPad? As an FYI - I tried the same SIM in my friend's iPad Mini and had the same results Any help is appreciated Thanks!
