Also there’s other ways of leaking your IMSIs, EAP-SIM and carrier wifi for example.

No idea yet how widespread the implementation is as I’m teaching myself all of this in my spare time!

EAP-SIM and Carrier WiFi is also not very difficult to disable. In any case, an IMSI leak is not as bad as an IMEI leak.

Also ... define “not difficult to disable” when it’s not exposed in the UI.

A *# code doesn’t count here also ;)

For me, not difficult to disable means that it takes less than 15 minutes to do so. difficult to disable would take hours and require specific knowledge.

I think you May have that backward. But why do you think this?

Because the IMSI is changed much more easily than the IMEI, and if in LTE only mode is only temporary.
