It works with a sm card . If the Sim card is too big for the slot you can get it cut to fit. The phone will work in any country, just use the country'so Sim card.

As long as you are going to use it with a GSM carrier, it will work. It obviously won't work with CDMA.

Hi, I am using it in Dubai where we have GSM. I do not think it will work with CDMA because the concept (SIM etc.), inbuilt-system and even the frequencies are different. I suggest you go for Samsung Versions of similar phones. I think 3580, 3590 are similar. Also, there is a CDMA version of RAZR too but I do not know the model. You might have to research a bit more. I used GSMArena.com for my search. Hope this answer helps!

All GSM phones such as ones for AT&T or T-Mobile needs SIM card but for Verizon phone which works on CDMA network don't use SIM card but need access code. The packages come with SIM cards and access code so no matter what phone you have you are covered

This type of phone will work anywhere in the world,however you have to make sure you purchase the right phone for the type of network you intend to use it on. For CDMA you have to specify that you need that type of phone when you make the order.Gsm will not work on a network that DOES NOT use sim cards.

It requires a CDMA card if you're getting Verizon service, as opposed to the GSM SIM card that a lot of cell phone companies require. I only remember going to a Verizon store, and they took care of loading it for me.

Wrong, cdma was used back when there was no such thing as sim cards, you can purchase this phone and since we sell them unlocked already any company will work. As long as you have a working sim card.

This is a Verizon phone so it uses CDMA not GSM. You have to use Verizon as your carrier.
