What year was the first mobile phone used?
Dr. Martian Cooper in 1974 invented the cell phone for Motorola. Bell Labs in 1947 made the first prototype , but Cooper is given credit for the first working cell. The phone was only sold to the government agencies until 1984 when it finally went public. The first cells were big, expensive, and would drop calls. Cell towers hadn't been built so service was hit and miss. Charges for calls were by the minute. There were no smart phones, Internet, cameras, or other things on the first phones. These will come much later.
