Basic assumption is that you all have such basic equipment as radio but it isn´t so widely used anymore except by robotic gangs that have banded together for survival, thou they use encrypted channels. Also it is a common joke among more veteran survivors how every time  there´s a new pulse, newly awakened bots flood the radio channels :DDD
