The emergency call function on mobile phones is just a gimmick

It was recently reported by the media that when mobile keypad is locked or without a SIM card inserted, it can only dial 112 and 911. Emergency numbers such as 110 and 119 cannot be dialed. Careful readers have noticed that the callable numbers are actually emergency numbers in EU and US. Why domestic emergency numbers are not set in mobile phones? Reporters interviewed people in the industry regarding this matter.
