Hi hantwister
Currently, SIM Change detection feature is not compatible with Google Project FI device, but we may expect it to be taken care in the future. At the moment the only way to avoid SIM change notifications is to disable the SIM change detection feature. Please refer to the thread Frequent messages saying SIM card has been changed, on how to disable the SIM change detection on Sophos Security. Let me know if this helps resolve the issue.
