They should have built a solution where the phones that haven't been tested get cut off, but get an SMS telling them to activate the phone, call SOS once. For the first SOS call, they intercept it, check that the phone was able to make the call, then unblock the phone, and after that, allow SOS calls as normal.
That would require "actually doing work" though.
