2G or GSM cellular network is vulnerable to IMSI catcher. Yes, only 2G or GSM network is vulnerable to IMSI catcher. 4G or LTE or 3G network is not vulnerable to IMSI catcher. But you would say that srsLTE or OpenLTE is an IMSI catcher for 4G or LTE networks. But srsLTE or OpenLTE IMSI catcher is not fully effective.

So one thing, can't 4G, LTE, or 3G networks be intercepted in the cellular network. No, IMSI capture works properly on 2G or GSM networks, but if we downgrade 4G, LTE, or 3G network to 2G or GSM network, we can sniffing the cellular network and call SMS and location.
