The short answer
No. A fax is received by a fax machine or a fax server attached to a landline, and a mobile number has neither. The form rejects mobile numbers.
If the recipient only has a mobile phone, an email with the document attached is the practical alternative. The mobile fax page explains what is possible from a phone.
Why mobiles are excluded
A fax call is a short data exchange between two fax modems. A mobile phone does not answer with fax tones, so the call connects to nothing and ends without a document.
That is why the service validates the number before the send and rejects the ranges that belong to mobile networks, such as 06 and 07 in France.
What to do instead
Ask the recipient whether the organization has a landline fax number or a fax-to-email address. Many offices keep one even when the staff work mostly on mobiles.
Failing that, sending the file by email is faster and keeps the quality intact. You can still use Faxturbo from a phone to send to a landline.
