None of us are allowed to call neither receive any call from a stranger unless the mobile or telephone number is being registered with the telecommunication depth of the united states of america because in the following year, that was in 1925, both soldiers and telecommunication network was jammed because a soldier received a call from an outsider or I rather call it a stranger which was later known as terrorists plan And that led to the death of many soldiers because they couldn't communicate before the bastards terrorists ambushed them
