Unfortunately, sending a fax directly from an iPhone without using an app is quite limited since iPhones don’t have built-in fax functionality. Most free methods still require using a third-party website or app. However, you can try online fax services like FaxZero or GotFreeFax through Safari—just upload your document and enter the recipient’s fax number. It’s not fully app-free, but it doesn’t require downloading anything, and some sites offer a few free pages per day.
