2017, https://arxiv.org/abs/1702.04434 > IMSI Catcher attacks are really practical for the state-of-the-art 4G/LTE mobile systems too. Our IMSI Catcher device acquires subscription identities (IMSIs) within an area or location within a few seconds of operation and then denies access of subscribers to the commercial network. Moreover, we demonstrate that these attack devices can be easily built and operated using readily available tools and equipment, and without any programming. We describe our experiments and procedures that are based on commercially available hardware and unmodified open…

Just as a point of interest around 4G/LTE, it's worth noting that (many/most) LTE networks don't support calling natively over LTE. At least not for a lot of the handsets in the hands of their customers. Unless your handset implements the all-IP Voice-over-LTE spec (which was an after-thought to original 4G), all calls are handled by the circuit-switched fallback (CSFB) process, where calls go over the legacy 2G or 3G networks. Since many networks don't actually have VoLTE fully implemented and working yet (and many popular Android handsets have quirks/bugs/issues around it, coupled with MNOs…
