What file format is best when faxing from a phone?
PDF is usually the most reliable. If you start with photos, combine them into one PDF so pages stay in order.

Create a single multi-page PDF, then upload that one file. Numbering pages inside the PDF (1/7, 2/7…) helps if the recipient prints it.
Why did my mobile fax fail?
The most common causes are a wrong number, a busy line, a weak connection while uploading, or an unreadable/oversized file. Retry later and double-check number formatting.

Avoid public Wi‑Fi for sensitive documents. Prefer cellular data or a trusted network, and delete local copies after you send.

Yes—enter the full number with the country code (for example: +44 for the UK). See international faxing.
