How to open OGV on iPhone?

Can you provide a step-by-step guide on how to open OGV files on an iPhone? Are there any specific apps or tools that I need to download or install in order to view these files? Also, is there a possibility that my iPhone may not support OGV files at all, and if so, what are the alternatives? It would be greatly appreciated if you could elaborate on the process and provide any tips or tricks that could make the process easier or more efficient.
