4G SIM card on iPhone??

[idevices.are.best]

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.

How can I use 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.
