How to fax from an iPhone
An iPhone can't send a fax on its own: faxing needs a phone line that speaks the fax protocol. What it can do is hand your pages to a service that dials the fax machine for you. You can do that right here in Safari, without installing anything.
- Type the fax number, area code first.
- Tap “Take a photo” for paper pages, or “Add PDF or photos” to pick a file from Files or your photo library.
- Check the page count and the price, then tap Send and pay with Apple Pay or a card.
- Leave the page open or come back later. You'll see when it's delivered, with a receipt you can save.
