Install a third-party app to send a fax from your iPhone.

We’ve likely all been there: You need to send a quick document to someone insisting the information arrive via fax, yet you no longer have access to a fax machine, and you may not want the complexity of an efax app. Thankfully, it’s easy to send a fax using just an iPhone using the FAX.PLUS app. No fax machine or fax number is needed.

With the FAX.PLUS app, you can fax an initial 10 pages from an iPhone. Additional credits can be purchased as needed if more than 10 pages need to be faxed. Other available monthly and annual plans support from 200 to 4,000 fax pages per month. An enterprise plan may be of interest to health care organizations because it allows businesses to sign a Business Associate Agreement with the vendor in order to comply with the Health Insurance Portability and Accountability Act, known as HIPAA.
