It's the same, a cell phone is a mobile phone. Cell comes from cellular which refers to the cellular towers or transmission towers, which connect your phone to the telephone switch or system. In the early days of wireless communication (the analog age) transmission towers broadcast at a 15 mile range on land and 50 miles over water. This radius created a circular area of coverage or a "cell." Cells were overlapped to provide continuous coverage for people traveling along roads and over highways. Eventually this spread out to cover the areas in between transmission lines. Wireless communications technicians still refer to transmission towers and their coverage area as cells.

Unfortunately at the time of major natural disasters such as earthquake, cyclone, flood and landslide, the regular telecommunication infrastructure of public wired and wireless (mobile) telephones get severely damaged and become nonfunctional. This mainly happens because of the damaged cables and cellular transmission towers or disrupted power supply to operate the telephone exchanges and cellular transmission towers. The wireless radio communication network of Police and Civil authorities also gets affected due to damaged transmission towers. During this emergency situation, the communication traffic goes beyond its capacity which leads to congestion of the network or in worst case, complete failure of network.
