Question: Which company developed the first mobile phone?
The first mobile phone was developed by Motorola. On April 3, 1973, Martin Cooper, a Motorola researcher and executive, made the first mobile telephone call using a handheld device. He placed a call to Dr. Joel S. Engel of Bell Labs, his rival at the time. The device used for this call was the Motorola DynaTAC 8000X, which later became commercially available in 1983.
