Send and receive one-off faxes within the UK?

Question

I'm looking for software/app where I can send or receive the faxes within the UK.

I've tried Fax Burner, FaxZero, but they all work in the US (basically the disposable number is US-like) and my sender doesn't want or can't send international faxes.

The question is similar to a USA question, but this focuses on the UK.

Preferably free of charge (within certain limits) and run on OS X/iOS devices, but I'm open to on-line services as well.

Answer 1

There is Faxonline which provides an software/app (Faxapp for Windows PCs, Macs, iOS and Android) as well as on-line access (faxonline).

Works within the UK, and you can get your fax number during the registration. There are available free faxpages per each month.
