Comcast operates as a mobile virtual network operator (MVNO) and primarily uses Verizon's network, which is based on CDMA technology. However, Comcast also supports GSM-based services through partnerships with other networks. Therefore, while Comcast itself is not strictly GSM or CDMA, it utilizes the CDMA network for its mobile services.
Code Division Multiple Access or CDMA cell phones utilize a technology that permits the use of several frequencies at the same moment to send and receive data and voice transmissions. CDMA is newer radio technology that is designed to compete with the older Global System for Mobile Communications (GSM) network. As a result, CDMA phones cannot use GSM cell towers. Another difference is that GSM phones use SIM cards while CDMA phones do not.

The Sony Xperia Z does not support CDMA networks; it is designed primarily for GSM and UMTS networks. This means it is compatible with carriers that use GSM technology, such as AT&T and T-Mobile, but it cannot be used on CDMA networks like Verizon or Sprint. If you need a device that works on CDMA, you would need to look for a different model that specifically supports that technology.
GSM = Global System for Mobile communications. CDMA = Code Division Multiple Access.
