Martin Cooper invented the first cell phone in 1973 while working at Motorola. The first cell phone, released by Motorola, was called the DynaTec phone. It weighed 5 pounds, had a battery life of only 20 minutes, and cost $4,000. Cell phones have since evolved greatly, becoming smaller, lighter, more powerful and capable, and much more affordable. Concept phones of the future suggest designs that are flexible, self-cleaning, have advanced projection and printing capabilities, and can perform additional functions like translation and food preparation.

phone service.
