I travel a lot and don’t always have reliable Wi-Fi. Do I need a strong internet connection to fax from my phone from anywhere?

In my experience, a fax from a phone needs some form of internet connection—either Wi-Fi or mobile data—because the file has to upload to the service’s servers before it’s faxed out. The good news is you don’t need super fast or perfect Wi-Fi; most services handle uploads over mobile networks just fine. I used to worry about connectivity until I read useful explanations like in https://www.techspot.com/news/106844-ho ... tless.html . If your connection is very weak, you might have to wait a bit longer for the upload, but it still works. My tip: check the app’s upload progress and confirm when the fax is sent before closing the app.
