I am using the old sim from my backflip since the new one they gave me with the atrix didn't work! Does it matter what sim you are using with 4g?

AT&T has just been capping them and HSPA+ is in almost no cities.I am using the old sim from my backflip since the new one they gave me with the atrix didn't work!
