Your Smartphone Becomes a Fax Machine: How eFax Changes the Way You Work

Image source: efax.co.jp (official website) — Cited for identification of the reviewed product
"Fax from a smartphone?" — That was the slight hesitation Yamada felt at first. After all, when he thought of faxing, he only pictured an office machine where you load paper and dial a number. But eFax's system is surprisingly simple. A dedicated fax number is set up for you in the cloud, and when someone sends a fax, eFax's servers automatically convert it into a PDF. You can then receive it on your smartphone or PC via a dedicated app or even email. Sending a fax is just as easy: attach a PDF or image file to the app, enter the recipient's number, and you're done. No paper, no ink, and no phone line required.
The value of this "line-free" approach truly shines in an era where you can work from anywhere. A landline contract typically costs around ¥1,500 to ¥2,000 per month, plus you need to buy a fax machine and find space for it. With eFax, there's no equipment and no wasted space. Users have commented that "it's convenient not needing a fax machine and being able to manage everything as PDFs," and it's praised as a way to save space in a home office and go paperless.
Used by over 12 million people worldwide, eFax has a proven track record with a wide range of users, from individuals to corporations. As one review puts it, "It's a lifesaver being able to check faxes on the go," making it a natural fit for a work style where you never miss an important business document, even when you're away from the office. Checking a purchase order that arrives during a meeting at a café and replying on the spot — eFax seemed like a perfect match for the ideal workflow Yamada had in mind.
Benefits of eFax: What You Gain by Adopting It
"I'm happy just not having to go to the convenience store, but what actually changes?" — Faced with the monthly fee of 1,980 yen, Yamada took a closer look at the specific advantages of eFax. Below is a summary of the benefits that emerge from publicly available information, framed from the perspective of what changes after adoption.

▼ List of eFax Benefits
| Benefit | Specific Details and Yamada's Perspective |
|---|---|
| No fax machine or phone line needed | Eliminates equipment purchase costs and line contracts, freeing up limited space in a studio apartment. |
| Send and receive on the go | Check new faxes via the smartphone app and reply instantly. Work doesn't stop while traveling or out of the office. |
| Paperless with PDF management | All received faxes are saved as PDFs, making search, forwarding, and cloud storage seamless. No more paper filing or risk of loss. |
| Choose area codes from all 47 prefectures | Get a number that matches your business location, and keep using it even if you move without changing the number. |
| Cancel anytime, no strings attached | No minimum contract period or cancellation fees, so you can easily stop if it doesn't suit you. |
The monthly fee of 1,980 yen includes up to 150 pages each for sending and receiving. For users like Yamada who only use a few pages per month, there's rarely any concern about overage charges (10–11 yen per page). Additionally, integration with cloud storage services like Dropbox and Google Drive allows automatic saving of received faxes into client-specific folders. The ability to reduce both paper and hassle aligns with the real-world feedback found on multiple review sites, such as "easy and convenient" and "less wasted printing." While the monthly fee isn't zero, factoring in convenience store fax costs, travel time, paper expenses, and line charges, it becomes a rational choice for low-volume users. That's why it can be seen as an investment worth trying without much risk.
Speaking Honestly! The Light and Shadow of eFax Reviews and Ratings
"Could there be a catch with something this convenient?" — That's what Yamada thought as he thoroughly checked multiple review sites. While there are many positive comments, some harsh criticisms also stand out. Let's follow Yamada's changing feelings as we honestly pick through both the good and bad reviews.
■ Positive Feedback: High Praise for Ease of Use and Going Paperless
"It's convenient not needing a fax machine and being able to manage everything as PDFs." (Multiple review sites)
"It's a lifesaver being able to check faxes even when I'm out." (Multiple review sites)
"Simple and convenient," "Reduced unnecessary printing" (Multiple review sites)
What these comments have in common is a sense of satisfaction from being freed from location and paper. In particular, "reduced unnecessary printing" perfectly matched the style Yamada envisioned: "It's enough to just check when needed."
■ Negative Feedback: Dissatisfaction with Support and Stability, Plus Limitations to Know
"The support response was poor, and it was unpleasant even when canceling." (Multiple review sites)
"There are frequent outages where faxes can't be sent." (Multiple review sites)
"The pricing is high," "Sending takes too long" (Multiple review sites)
The mechanical support responses and the transmission failures reported by some are certainly points of concern for business use. However, looking across multiple review sites, it appears these issues don't occur daily for all users. Additionally, complaints about high pricing often come from comparisons with other companies' low-cost plans, and don't fully account for eFax's unique features like nationwide area code coverage and cloud integration in an overall evaluation.
Furthermore, when considering actual use, you should be aware of the following limitations:
- Existing fax numbers cannot be transferred: eFax only issues new numbers. You cannot keep your current number.
- Sending to toll-free numbers (e.g., 0120) is not possible: If the recipient uses a toll-free fax number, you cannot send from eFax.
- Support is primarily via web and email: If you want to resolve issues quickly over the phone, you may find this somewhat lacking.
Even after seeing these negative aspects and limitations, Yamada processed them in his own way: "For me, who mainly sends a few pages a month and doesn't use toll-free numbers, these probably aren't deal-breakers." The fact that he can cancel anytime without penalty gently nudged him toward that decision.
In-Depth Comparison: eFax vs. Other Options – Which One Offers Better Value?
"But I still want to take a proper look at the alternatives," said Yamada, the savvy shopper, as he began comparing eFax with other internet fax services and traditional fax machines. Below is a table comparing eFax, J-FAX (a representative internet fax service), and a traditional fax machine with a landline.
| Comparison Criteria | eFax (Internet Fax) | J-FAX (Example of Another Internet Fax Service) | Traditional Fax Machine + Landline |
|---|---|---|---|
| Monthly Base Fee (tax incl.) | 1,980 yen | Varies by provider | Line fee approx. 1,500–2,000 yen + equipment cost |
| Send/Receive Limits | Up to 150 pages each per month free | Varies by plan | No limit (call charges apply per use) |
| Overage Charges | 10–11 yen per page | Varies by plan | Around 50 yen per page (when using convenience store fax) |
| Area Code Coverage | All 47 prefectures nationwide | Varies by provider | Depends on landline contract area |
| Smartphone App Support | Yes | Varies by provider | — |
| Fax Machine Required? | No | No | Yes (separate equipment purchase cost) |
| Paperless Management | PDF storage, cloud integration available | Varies by provider | Generally not possible (paper output is standard) |
| Free Trial | Currently not available | Varies by provider | — |
| Cancellation Terms | Cancel anytime (no penalty fee) | Varies by provider | May incur penalty fees depending on line contract |
Other internet fax services like J-FAX offer plans with lower monthly fees than eFax. However, they often lack differentiation in areas like area code options and cloud integration, so the best choice depends on what you prioritize.
Traditional fax machines with landlines offer the peace of mind of unlimited usage once set up, but they come with higher costs for equipment, installation space, and consumables like ink and paper. For someone like Yamada, who only needs to send a few faxes per month and doesn't want to keep a machine at home, this option is clearly overkill. Now that he knows which option suits him best, Yamada is ready to form a concrete plan for signing up.
3 Simple Steps from Signing Up to Using eFax
So, how easy is it to actually start using eFax? Here’s a quick 3-step guide to the process, from signing up entirely online to getting started. Since approval can sometimes take a few days, if you need a fax number right away, be sure to start the process with plenty of time to spare.

Step 2: Choose Your Preferred Fax Number Select a number from area codes across all 47 prefectures that suits your business or daily life. Since this affects your external image—like Tokyo’s “03” or Osaka’s “06”—it’s a nice perk to be able to choose carefully based on your needs.
Step 3: Start Using It Right After Approval Once your application is approved, you can download the smartphone app, log in, and start using it the same day. The initial fee is 1,100 yen. Monthly payments can be made by credit card or bank transfer. While eFax currently doesn’t offer a 30-day free trial, there are no minimum usage periods or cancellation fees. For Yamada, who is trying internet fax for the first time, the biggest relief is being able to start casually with a “try it for a month in real use” approach.
