Yes, if in GPX Format.

Do you mean can you view POI files on cell phones? If the POI file is in GPX Format, then yes, there are apps for mobile devices that read GPX files and display the locations on a map. Some of the apps are free, some not. I developed an iPhone app called GPX-Viewer for $2 that is very popular and can display GPX files. Hope that helps!
