Didn't Apple once upgrade IOS so that dialing any number used by emergency services in any country would connect to the local emergency services (sort of like the eay while in UK 999 is the official emergency number that 112 and 911 also connect) not realizing the the Vodafone voicemail number was the same as the emrgency number somewhere in eastern Europe or Asia so that anyone checking their voicemail was being connected to a 999 operator!
