New Radio Non-Standalone millimeter Wave (NR NSA mmWave) uses the 4G LTE protocols for the control channel and 5G NR on the mmWave spectrum (24.25–52.6 GHz) for the data channel. It provides much of the speed of 5G without any of the additional security benefits. Android phones will list this as a 5G connection, but it is not protected against modern stingray attacks.
