How to fax and fax a document from your smartphone


We all know how to sign a PDF document from your phone, tablet, or other computer and email it to someone. However, some organizations still don't accept documents via email, and you may need to fax documents instead.

Unfortunately, you can't use your smartphone network as a fax machine or a modem connected to a telephone line. You'll need to rely on a third-party app or service that sends faxes on your behalf, just like you occasionally fax from your home using a real fax machine.
The service is not free:

You won't find an app that lets you send an unlimited number of faxes for free. Every app you find here will cost you money to use regularly. Some apps may let you send a few pages for free, but that's it. These services must pass through the landline phone network for you. Your smartphone can't work as a modem, so you rely on service servers to do heavy work.

However, although this will cost you, it can save you money and be more convenient than paying for fax machines from a store near your home, or buying your fax machine and delivering it to a landline. Both are likely to be much more expensive if you just need to send some faxes.

This method also allows you to do everything entirely electronically. You can sign and fill out PDF documents on your phone and fax them. Or use your phone's camera to scan and fax paper documents.

iPhone or Android apps:

Look for "Fax/Fax" in the App Store or Play Store and you'll find a few options, but there's actually no free app, and few offer a limited number of free fax pages before they start collecting fees from you.

But there is a bigger problem — the vast majority of the time when you need to fax something, you send a document containing personal information — such as health care and government or banking documents.

You should not trust anyone who deals with your personal information by fax. So we have some recommendations for you.

If you're going to send sensitive, time-sensitive, or work for a company and try to choose a professional service, RingCentral Fax, which is partly owned by Cisco and AT&T, maybe the best choice for your needs, especially since they have a lot of great security features and support for many users with different fax lines.

Temporary use:

If you just want to send some faxes every now and then, you can also choose eFax, well known as the company that invented fax digitally. They have a good mobile app that lets you send and receive faxes.

We also recommend MyFax, which allows you to send up to 10 free pages without having to pay. This doesn't sound like much, but it's more than most people have to fax it every year. If you need to send more pages each month, you can upgrade to a regular plan.

Fax via e-mail

If you use Windows Phone, Blackberry, Fire Tablet, or any other operating system, you can always subscribe to RingCentral, eFax, or MyFax and then use the website to send a fax – or you can use fax via email.

Almost all providers allow you to send faxes by sending an e-mail document to the number you're trying to fax to, with a dedicated end. For example, if you want to send something to 1112223333, you can send the document to an email such as:



The ability to send faxes via email means that any mobile device can easily send faxes without having to install an additional application.
The bottom line:

There is no complete and comprehensive fax application. If you need to send quite a few pages continuously, a subscription-based service like RingCentral or eFax may be the best. If you just want to send a quick fax, MyFax is probably the best for you.

If you're using another smartphone basic system (such as Windows Phone), your best bet is to find a fax service that lets you fax by email, which is the easiest and best way to send faxes anyway.
