Can i download iso windows on phone mobile

It wouldn't work with a phone. The phone wouldn't be able to hold the amount of data, and there can be other issues. I have yet to see it work.

You can, however, try using your phone as a "HotSpot" for internet for your computer (works like WiFi) and then download it directly to the computer. Really depends on if you have enough data though, and if your phone can be used as a "HotSpot".

If it is at all possible it would be done this way...

1. Go into "Settings" and in the "Wireless & networks" section tap "More".
2. Now tap "Tethering & portable hotspot".
3. For "Wireless Tethering" tap "Set up WiFi hotspot"
4. On this new screen you will see options for a "Network Name", "Security", "Password" and "Network Band". You can change them or keep them as is. It is really up to you.
5. Now you would just need to search for the hotspot by name using the second device.

NOTE: While a WiFi hotspot feature is built into Android, some service providers/carriers, especially in the United States, hide it. You would then need to see if you can locate an app that you can install to help with this.
