Answer 1

Phones relay conversations via cell towers. Walkie talkies send signals directly from device to device. Both technologies have benefits and draw backs. Phones need smaller radio since signal only needs to reach nearest cell tower. Walkie talkies are free, since you don’t have to pay for subscription.
