FAQ

Is there a truly free fax app for iPhone?

Yes, several apps offer free tiers or trial credits. For example, Fax Burner provides 5 free sent pages and 25 received pages per month, while Fax.Plus gives 10 free pages upon signup. However, completely unlimited free faxing does not exist due to telecommunications transmission costs.

No, iOS does not include a native built-in fax application. However, you can scan physical documents using the iOS Notes or Files app, export them as PDFs, and send them using mobile tools like Municorn Fax App or web-based email-to-fax services.

What's the catch with free iPhone fax apps?

The primary catch with free fax apps is that free pages are capped or attached to short trial periods. Many App Store tools prompt for auto-renewing weekly subscriptions, so users should carefully check terms and page limits before initiating multi-page transmissions.
