When using EE SIM cards, CP LTE modems try to connect requesting IPv4V6, but the EE network rejects them because wants LTE to only use IPv4.Any Cradlepoint device running NCOS 7.21.97 and above.When CP 5G modems try to connect requesting IPv4V6, the EE network only gives the modem an IPv6 context. The modem then engages its XLAT feature and hands the router the IPv6 address from the network and a local non-routable IPv4 address which is 192.0.0.2.The current available solution to overcome this problem is to use local and remote identity or hard code the modem to request only a IPv4 context.
