Frequently Asked Questions

Mobile fax is the ability to send and receive faxes using a mobile device such as a smartphone or tablet. Faxing can be done via email, a mobile fax app, or a cloud-based fax service. Mobile faxing is beneficial because it allows users to stay connected while on the go.

Mobile fax is becoming increasingly important as more people work remotely and regularly send and receive documents. It is also useful for businesses that need to send confidential and sensitive documents but do not want to use traditional fax machines.

There are many advantages to using a mobile fax service, including sending and receiving documents anywhere, at any time. Users can also take advantage of features like e-signatures and secure file sharing. They can easily scan documents using the camera and send them directly to a fax number.

To get started with mobile fax, you need a phone with an internet connection. You can then sign up for a service like iFax and start sending and receiving faxes. You can sign up for a free account and try out the features.

Mobile fax is a great way to stay connected and get work done while on the go. It is convenient, easy to use, and can be a lifesaver when you need to send or receive important documents. Whether you are a business owner or a busy professional, mobile fax can help you stay connected and get work done without printing or carrying a bulky fax machine.

The average person typically uses a fax machine in two ways: sending or receiving documents. But what many people don’t realize is that there are two types of faxing: mobile faxing (or mobile fax) and traditional faxing (or fax). So, what’s the difference between the two?

Mobile faxing is a type of faxing that allows you to send and receive documents using your smartphone, tablet, or laptop. This means that you can fax documents even when you’re on the go. It’s your mobile fax machine. On the other hand, traditional faxing requires a physical fax machine. This type of faxing is typically used in office settings.

One of the main advantages of mobile faxing is convenience. With mobile faxing, you can send and receive documents anytime, anywhere. All you need is an internet connection and the mobile app for faxing. Traditional faxing, on the other hand, can be quite limiting.

You can only send and receive documents near a physical fax machine. Another advantage of mobile faxing is that it’s often more affordable than traditional faxing. You don’t need to invest in a physical fax machine.

Finally, mobile faxing is more environmentally friendly than traditional faxing since it doesn’t require the use of paper because you fax from computer and you save more money instead of buying ink or toner.

Mobile faxing has been around for a long time, and it has been improved as app publishers develop the features to make it more convenient for everyone. So how does it work?

Mobile faxing allows you to send and receive faxes using your smartphone or tablet. There are a few different ways to do this, but the most popular method is to use an online fax service like iFax.

These services provide you with a dedicated fax number for sending and receiving faxes. When you need to fax, you simply attach the document (in PDF) to the application and send it to the fax service’s email address or directly to the recipient’s fax number.

The service will then convert the document into a fax and send it to the recipient’s fax machine. Similarly, when you receive a fax, the service will convert it into a PDF file and email it to you. This makes it easy to view and store your faxes, even if you’re away from your office.

And because most online fax services offer cloud storage, you can be sure that your documents are always safe and accessible. So there’s no need to worry about losing important papers or having them stolen. Mobile faxing is a convenient way to stay connected, even when you’re on the go.

That’s how the iFax mobile faxing app works, too. The user can use a mobile phone to scan a document on hand using the built-in OCR scanner of the app and then attach it. Fill out the contact information for faxing, such as the fax name, number, email address, comments, etc. Once done, the recipient will receive it as if the fax was sent via a physical fax machine.
The recipient may also reply to the sender and fax documents. Since the sender is using the iFax mobile faxing app, he will receive a notification via email about the incoming fax. When he views it on the iFax main dashboard, the fax is attached as PDF.

With the proliferation of mobile devices, it’s no surprise that mobile fax is gaining in popularity. But is there such thing as free mobile fax service?

There are a couple of different ways to send faxes from your mobile device. You can either use an app or a service. Some apps, like iFax, allow you to fax from mobile phone for free for seven days. It will give users more time to explore the basic and advanced features. After the trial period, you can upgrade anytime. If you need to send more faxes after the trial, you’ll have to sign up for a paid subscription.

There’s also a pay-per-fax option that lets users pay for the service for one-time. After this, you don’t have to pay for anything. The free online fax services are mostly offered as free trials. They also limit the number of pages you can send once the credits are used up. And if you need to receive faxes, you’ll likely have to pay for that. So while there are some free mobile fax app options available, you’ll probably have to sign up for a paid plan if you need to fax regularly.

iFax has three subscription plans that users can pay monthly or annually. If you choose the latter, you get a 20% discount, which is a huge saving. Visit the pricing plan page to compare what’s included in each package.

iFax is the best mobile fax app for many reasons. First, it is highly user-friendly and designed to make faxing more efficient and affordable.

You can fax from your phone or tablet with just a few taps, and the mobile faxing app automatically syncs with your contacts, so you can easily send faxes to anyone in your address book.

Second, iFax offers superior security features to protect your confidential information. All faxes are transmitted over a secure connection, and you can set up a pin code to restrict access to the app using two-way factor authentication.

iFax is also HIPAA and GLBA compliant, which means all faxes are secured, and the service can handle even the most sensitive data in healthcare, finance, legal, and other industries.

Third, iFax is more affordable than other mobile faxing solutions. The basic plan starts from $8.33 per month, is billed annually, and is one of the cheapest in the market.

Subscriptions are upgradeable and cancellable, giving users full control over how long and when to use the service. There’s also a pay-per-fax option, so you only pay for the faxes you send.

And finally, iFax offers top-notch customer support. If you have any questions or problems, our team is always here to help 24/7. For all these reasons, iFax is the best mobile fax app today.
