On the majority of mobile phones the SIM card slot is located under the battery. Remove the back cover and the battery to reveal the SIM slot. The SIM card has a chamfered corner and this must be placed into the slot to match the chamfer.

The sim card appears to be inserted into a slot next to the memory card. You will have to remove the battery cover and battery to do so.

Hi, DONT CUT SIM!
Sim cards on the samsungs slot into sim reader which is found under battery. If you remove the battery you should see where it goes. The slot you are referring to sounds like the memory card slot which is an expansion slot if you want to increase the memory size for file storage. Hope that helps?

It depends on your carrier or phone model.

Verizon Wireless still uses the CDMA network. CDMA gets the phone user ID from a programmed chip hardwired to the phone instead of a SIM card.

Because of this, there is room underneath the battery cover, south of the battery on the right side of the compartment for a mini-SD card.

Other carriers such as T-Mobile, Cingular/AT&T DO use SIM cards to store user ID, so there is not room for a memory card.

I do know that the MotoRazr2 V9 from AT&T DOES accept Micro-SD cards.

But if you have a GSM carrier such as T-Mobile or AT&T, the Razr V3 does not have a card slot.
