Pager is a one way communication i,e it can be used only to receive messages. It is beneficial where landlines are not available or the person is mobile. Like Vanita, Naina has to call pager number and pass her message, which will be received and transmitted by exchange person/machine to Sam's pager. Then if he wants to communicate, have to find landline to call. Here N is stationary at home so she doesn't need a pager.
How it will help Samaina? Hmmm N can message him, aaj maine samose banaye hain toh Shibani ke ghar mat khana. 😆or papa ghar pe nahi hai or main tumhare bachche ki maa banne wali hun😆etc etc
Oh achcha, got it. 😃
But aise one sided communication se to apna mobile phone better hai, ab pata chala ki sab mobile ke aate hi pager ko kyon bhul gaye 😆.
Maza aa gaya and I second @Umam. Your titles are
