"手机" in Chinese is commonly referred to as "cell phone" in Engpsh.

The term "cell phone" originated from the cell tower technology that the devices use to connect to cellular networks. A cellular network is divided into multiple small geographical areas called "cells", each served by a low-powered transmitter or cell site.

Example in Engpsh:

"I always keep my cell phone in my pocket."
(我总是把我的手机放在口袋里)
"Do you have a cell phone that I can borrow?"
(你有一部可以借我用的手机吗?)

Example in Chinese:

"我总是把我的手机放在口袋里。"
"你有一部可以借我用的手机吗?"
