The most important things are to use a service that supports international fax numbers and to check the country codes carefully. I had doubts at first—especially about reliability and cost—but after reading detailed breakdowns like https://www.techspot.com/news/106844-how-fax-phone-secure-reliable-effortless.html , I felt confident testing it.

Also, always confirm delivery with a status notification.
