Cell Phones

Technically, the prototype for the first mobile phone was created in 1973. These early devices never made it into mass production because they were cumbersome and lacked a cellular network. Starting in the 1990s, mobile devices became increasingly popular. Today, they offer features like video calls, fitness apps, audio recorders and cameras.

How a Cellphone Works

At a very basic level, a cellphone is a two-way radio. It includes a radio transmitter and a radio receiver. When you call your friend, the phone transforms your voice into an electric signal. Then, this signal is sent through the radio waves to the closest cell tower. From the cell tower, the electric signal is relayed to your friend’s phone. At this point, it is converted back into sound so that your friend can hear your voice.

While the main goal is to send audio conversations from one person to another, phones can do many more functions than just voice calls. Modern Apple and Android phones can send text messages, take pictures and surf the web. In addition, your phone can play favorite songs or games. The most sophisticated phones have capabilities similar to a personal computer.

The Advantages of Getting a Phone

There are a number of reasons why you might want a mobile device. At a very basic level, mobile devices allow you to communicate with other people. While this communication can occur through a voice call, you can also use your phone to send text messages or video messages as well.

Take Photos and Videos

The majority of phones available have some kind of camera for recording images and sound. You can take photos throughout the day and share them on social media. Depending on your phone, you may also be able to store a large number of videos on your device.


This is the biggest reason why people get a phone. You can communicate with other people by calling or texting them. Plus, you can also download Snapchat, Facebook or other apps to communicate in other ways.


Your phone can help you become more organized. Most phones include options like calendars, notes and reminders. You can also use your phone as an alarm clock.

Online Banking

In recent years, banking apps have become more convenient than going to the bank. You can take a photo of a check to deposit money into your account. In addition, you can transfer funds and pay bills through the app.


Once you have a smartphone, you do not have to worry about getting lost again. Whether you have an Android or Apple device, you can use features like Google Maps to find local restaurants and shops. If you are driving somewhere new or going on a road trip, this feature is especially useful.

What Kind of Phone Should You Choose?

Choosing the right cellphone can be intimidating at first. Your first decision will be which provider you choose. You can use a prepaid service like Google Fi or Consumer Cellular if you do not want a contract. If you are using more data, you will probably want to use one of the major carriers such as T-Mobile, Verizon Wireless and AT&T.

Coverage Matters

No matter which provider you use, you will want to make sure there is coverage in your area. Large carriers like Verizon and AT&T have high-speed 4G service throughout the country. These companies are also working to build 5G networks as well. Before you choose a provider, you should input your address into the provider’s coverage map to make sure that they have options for your area.

Data Usage

If you go over your data limit, you may have to pay more money. At the very least, the provider will throttle your data speed. Before you pick a plan, you need to figure out how much data you will use each month.

Operating System

Finally, you should consider the operating system. Google’s Android platform works with a range of handset makers and has a number of customization options. Meanwhile, the Apple interface is popular for people who want to access videos, games, music and other content.

The following are the most important features you should look for when you shop for a new device.

  • Screen size.
  • Price.
  • Design quality.
  • Battery life.

If you get into an accident, a smartphone allows you to call for an ambulance. Whether you want to communicate with your friends or play games, mobile devices can help. With the right device, you can stay organized, take photos and respond to emails from anywhere in the world.
