GSM, takes a SIM card (actually 2 SIM cards), will not work with CDMA which is a different and incompatible cell phone radio standard.

Hi Gustavo,I was just commenting on the phone in general. I'm not selling this phone and I don't know if it is for GSM or CDMA. I can tell you that the LG G2x I have is a GSM phone from the US, and I have had nothing but issues with it.

GSM is a radio network for AT&T; & T Mobil cell phones And page plus & Verizon radio network is CDMA A locked phone has nothing to do with GSM or CDMA The lock is in the phone. it is a security code the owner establishes in the phone

i looked this phone up on gsmarena.com and it does say that because its a global it can be used on either GSM network or the CDMA. im not sure if this phone is unlocked but i have emailed a seller and they told me it was. my advice on that, email the seller that you want to buy the phone from and see what they say

CDMA, or Code Division Multiple Access, is a competing cell phone service technology to GSM, which is the world's most widely used cell phone standard. Google it :)

Since this phone operates on the CDMA system, check with someone who has a Verizon phone and find out how it works in your area. CDMA is generally operated by Verizon. The other system is GSM (a G at the end of the model number) and that is generally operated by AT&T.;
