“Cell phone” is short for “cellular phone”, and I will get to the reason why it is called that shortly. In most other places in the world, the common terminology is mobile phone. But in the United States, this connected mobile device is known differently – as a cell phone. But is it written as cellphone or cell phone?

In most other places in the world, this device that allows users to make and receive calls (and later, send and receive messages, and access the internet wirelessly) is called a mobile phone. There are some other names that are not quite common by which it is called. They include: handset, handphone, and handy phone, among others, but mobile phone is the most common term by which it is called globally. Why is it known differently in the land of the free?

Cellphone or cell phone - named after the network of Honeycomb cells
Cellphone or Cell Phone is derived from the concept of a network of cells similar to the structure of a honeycomb.

Historical Background

Mobile phone networks first appeared in the mid-20th century. Mobile phone networks are built on the concept of cells, with an entire network made up of connected cells. As a layman, think of it like a honeycomb to get a good picture of it.

The term “cellphone” has its roots in the word “cellular,” which was first used in 1753 to describe something consisting of or resembling cells. In 1947, two Bell Lab engineers named Douglas H. Ring and W. Rae Young proposed a network composed of hexagonal cells to allow mobile phones in cars to operate from one spot to another seamlessly, adding a new technological meaning to the word “cellular”.

This cellular network consisted of network towers or cell towers. Each tower was the centre of each cell, and each cell was linked to adjacent ones, just like the cells in a honeycomb. This remains the practice, the fundamental way that carriers and mobile networks operate, till date. And so, Americans began to call mobile devices cell phones.

An important thing to note is that “Cell phone” is short for “cellular phone”, which distinguishes it from other types of mobile phones, such as satellite phones. Satellite phones do not use a terrestrial network of towers for wireless communications. Rather, as the name suggests, they connect via wireless transmission from networks of satellites hovering in low orbit above the earth.

Cellphone or Cell phone? One Word or Two?

The more common term in use in North America is “cell phone”. This is how most Americans and Canadians write it. However, some have been known to write it as cellphone. I doubt that anyone gets marked down for writing it as either cellphone or cell phone.

For example, from time to time, I see articles in which the word smartphone is written as two words – smart phone. It irks me, to be honest. But I doubt that there is any committee of scholars giving out grades for how the word is written. I write it as smartphone all the time, because that is the widely accepted way to write it.

I have mentioned that “cell phone” is more common in American and Canadian English. The variant, “cellphone”, is sometimes used in British English, though the British more commonly refer to it as a mobile phone.

Language usage keeps evolving, and compound words or phrases have often become hyphenated or written as separate words, reflecting changing conventions in language and communication. This phenomenon is not unique to the question of whether it should be written as cellphone or cell phone. It is part of the broader evolution of language and the influence of regional and cultural factors.


The word “Cellular” is derived from the cellular network structure used in mobile telephony, where the service area is divided into small geographical cells served by individual base stations. This term gained popularity in the United States and became widely accepted.

What is the difference between cellphone and cell phone?

Nothing. It is a question of language. The terms “cellphone” and “cell phone” are two ways of writing the same word, which refers to a device that allows users to make and receive calls, send and receive messages, and access the internet wirelessly. Whether you write it as cellphone or cell phone is most likely dependent on your location and exposure. If you have been more exposed to American English, you likely write it as cell phone. If British, then cellphone (though more likely, mobile phone). If you did not grow up with exposure to either, I imagine that you have picked whichever caught your fancy. You probably never gave a thought to it.

So, either cellphone or cell phone is correct. It depends entirely on personal preference which one you prefer to use. The widely accepted term in North America is cell phone (two words). I recommend that you write it that way, too. If you do choose instead to write it as cellphone, nobody is likely to wonder what you are referring to, I am sure. Everyone knows what you are talking about. Before I wrap this up, I want to answer a question that I have been asked too often.

Is an iPhone a smartphone or cell phone?

A smartphone is an advanced type of cell phone or mobile phone. A dumb phone is another type of cell phone. A feature phone is yet another type of cell phone. And of recent, a new category of cell phone has been introduced; a smart feature phone. An example is the Alcatel Go Flip 3, running KaiOS.

To answer the question, an iPhone is a smartphone, which is an advanced type of cell phone.

Do you write it cellphone or cell phone?

Having clarified on the subject, I am curious and would like to know how you write it – cellphone or cell phone? And if you are from somewhere else in the world where mobile devices have another name, I’d like to hear from you. What is it called in your neck of the woods? Talk to me.
