This is due to the inefficiency of CDMA in utilizing radio spectrum, which is in short supply. As more people demand faster and better mobile services, CDMA channels are being reassigned to newer technologies. CDMA has never been a true worldwide standard, with many overseas countries also decommissioning it.
