Google it. I'm pretty sure all phone have the capability to be used as a mobile hotspot by using a free app, but the wireless carriers want you to pay extra for it. I have an app called "PDA net", but I think that is the one specifically recommended for my phone (Samsung GS4). If it had been left up to me to figure out how to make it work, I'd have been out of luck, but luckily SS#1 is a tech wizard and downloaded the app on my phone, figured out what corresponding app I needed on my laptop, and got it all set up and working. Now, all I need to do is plug my phone into my computer with the USB cord.
