What is difference CDMA and GSM?

CDMA stands for Code Division Multiple Access. One of the biggest differences between these two systems is that GSM phones use SIM cards to link a particular phone with its network, while CDMA phones don’t require a SIM card because the phone itself is linked to the network.

What are the different mobile standards?

Second-generation cell standards included Global System for Mobile (GSM), Integrated Digital Enhanced Network (iDEN), and Code Division Multiple Access (CDMA). Third-generation (3G) standards enable cell phones to go beyond simple voice and data communications.

Is Verizon switching to GSM?
