Can I submit an application from my mobile phone?

Unfortunately I do not have a laptop or PC at home. But soon I have to apply for an internship. I actually wanted to apply for OpenOffice and then as a pdf I do not think OpenOffice is an App or something like that I could use?

It is quite possible but not recommended. Can't you write a rough cut on a block and then ask a friend if you can type it on him?

Then go to an internet shop or go to friends or neighbors or family.

That's not what you do on a cell phone.

Take Polaris if you have Android. Or AndrOpen Office.
