Does Sony xperia Z support CDMA network?

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.
