True or false: all types of cell phones have operating systems.

True.
Hope this helps! :)

Hi there!

The answer is true because all cell phones have an operating system. an operating system (OS) is just the internal software system that displays the interface of your cell phone. An example of an operating system is the difference between Apple's MAC interface/system and Microsoft's Windows PC interface/system; it is simply the way the system for the computer of your cell phone is set up.
