Can you put a 4G LTE sim card in the verizon iPhone 4S??
If your SIM slot is unlocked, yes. You will still only get 3G services however.
If you have a Verizon iPhone 4s, it doesn't need to be unlocked.
You can use it but you will not get 4g.
You can't use 4G in an iPhone, the current iPhones only support 3G.
The iPhone 4S uses HSPA+ on AT&T, whereas the other iPhones don't. Therefore if you don't have a newer sim card on AT&T and haven't changed to a "4S" data plan then you won't get the HSPA+ (4gdata speeds).
Iphone 4S= 14.4mb per second
Iphone4= 7.2mb per second
FYI HSPA+ is just a sudo 4G network.

I know HSPA+ is not really 4g, but you still can't hit those speeds without an updated sim card. They shouldn't have called it 4g to begin with. It's 3G enhanced.
