Summary
Fax modems let computers send and receive faxes over a phone line, and while they’ve largely been replaced by online fax services, some businesses still rely on them because of legacy systems or limited broadband access. External USB modems are the easier option for most users, running between $15 and $40, though you’ll also need a dedicated landline. Mac users have been without compatible options since OS X 10.7, and for most people, an online fax service is the simpler path.

What Is a Fax Modem?
A fax modem is an accessory for a computer that allows you to transmit and receive data via a phone line. This device can be used to establish a dial-up connection to the internet or to send faxes via a dial-up connection.
Furthermore, fax modems may be located inside your computer or be attached via an external port. Faxes sent via fax modems may be printed at a fax machine or received using a fax software package or app.
Fax modems were the standard way to fax from a computer before online fax services became widely available. Today, most businesses that still use fax modems do so because they have legacy systems that depend on them, or because they operate in areas where broadband internet is unreliable.
Where Can I Buy a Fax Modem?
The best option for purchasing fax modems is to buy them online. There are several sites that sell them. A simple search on Amazon or other online marketplaces should help you find the correct device. You may also be able to find some models in retail office stores or electronics specialty stores.
When buying online, check reviews carefully and confirm OS compatibility before purchasing. External USB fax modems are generally easier to find and simpler to return if they don’t work with your setup.
What Else Do I Need to Send and Receive Faxes by Computer?
You have a couple of options available to you.
First, it should be noted that if you subscribe to an online fax service such as FaxBurner, fax modems are not necessary. Instead, you would simply use your high-speed internet connection, log in to the online service or app, and send and receive documents via the software.
If you choose to use a modem and a fax machine, however, you will need Windows Fax software and a dedicated phone line. You’ll also need a landline as VoIP doesn’t work with standard fax modems.
Is an Internal or External Fax Modem Better?
An external modem is connected to your computer or laptop through a USB or other port. This is used to connect to the phone line. These tend to be easier to install because you simply plug in and go. The downside is that the external modem is an additional piece of equipment that needs to be purchased and maintained.
An internal modem may come with your computer. In that case, there’s no need to do anything but plug the phone line into the computer, then into the fax.
If your computer doesn’t have an internal modem, you’ll need to open it to install the fax card. You’ll have to consult your manual for information on how to accomplish this. Please be aware that this may affect your warranty, if you have one. However, if this option is available, you won’t have to worry about having another external device to contend with.
How Do Fax Modems Work?
You’ve probably heard that familiar series of chirps and beeps when you send a fax. That’s actually data being sent via an audio signal. The fax modem converts the information in the document into sound on the sender’s side.
Then, it translates that sound back into data on the receiver’s side. Fax modems can communicate with other fax modems as well as fax machines. The receiver then gets their copy of the documents.
Fax modems use the T.30 protocol, which is the international standard for fax transmission over analog phone lines. The modem converts document data into audio tones, transmits them over the phone line, and the receiving modem or machine decodes those tones back into a readable document. The transmission speed depends on the modem’s baud rate, typically 14.4 kbps to 33.6 kbps on modern devices.
Why Do People Still Need a Fax Modem?
A fax modem is generally used with a dial-up internet connection and to replace a standard fax machine. There are still businesses that aren’t connected to high-speed internet and rely on machines like this.
Beyond internet connectivity limitations, some businesses continue using fax modems because their existing infrastructure and software are built around them, or because they serve clients whose systems require modem-based fax communication. For everyone else, an online fax service offers the same result with far less complexity.
How Much Does a Fax Modem Cost?
The price depends on whether the modem is internal or external, and the features it provides. You can expect to spend between $15 and $40 on a fax modem. There may also be labor charges if you need a professional to install it.
External USB modems tend to sit at the lower end of that range and are self-installed. Internal modems may cost slightly more if you need a technician to fit them. Don’t forget to factor in the cost of a dedicated landline, which generally adds $25 to $35 per month to the modem purchase price.
Is My Fax Modem Compatible With My Computer?
Compatibility is definitely a matter of concern. There are many operating systems for Windows, Apple, and Linux devices. While there are several compatible devices for Windows, there are none compatible with Apple since OS X 10.7. With Linux, it depends on the specific version.
Please be certain that your device will work with your computer before you make any purchases.
If you’re running macOS 10.8 or later, a fax modem is not a workable option. The best alternative for Mac users is an online fax service, which requires nothing more than a browser or email client and works on any operating system. Windows 10 and 11 users should also verify driver support for the specific modem model before purchasing, as driver availability varies.
Summing It All Up
Fax modems are still handy devices that add to your computer’s functionality. They’ll enable you to send and receive faxes using your computer, whether you’ve got a built-in one or purchase an external one. It’s not especially expensive, though you’ll need a dedicated land line to go with it.
That is, of course, unless you forgo the modem entirely and use an online fax service instead. In that case, as long as you have an internet connection, you can send and receive faxes from any computer or smartphone.
