Feature phone
A simple unconnected handset of the kind issued to children for emergencies. Sumati's father gave her one. It is the reason the first day is survivable.
Recovered
Simple, unconnected, durable. The kind of device that came back into use once everything else had become a surveillance surface.
Many children in Sumati’s world are issued one for emergency use only. The return of the feature phone is a considered retreat: back to minimalism, back to analogue, back to a handset that cannot be asked where it has been. It is usually described as nostalgia.
Her father gave her hers. That is the entire specification that matters.
