You don't need a special sim card just a newer one that's made for 4g. And you don't actually "need" it , I was able to use WiFi with my older gen sim.
I think its mostly for bete 4g connection.
I noticed a major dif in the phone when I put in the updated sim card.
Just ask tmo for a new sim I'd you don't have one, they shouldn't charge you for it, but then again....lol
