Do you tether your phone?
 

My cell plan gives me 5GB a month of tethering or hotspot. I never use it because I have my home WiFi and unlimited data on my cell plan. I would maybe use it if I was someplace that didnt have public WiFi and I was on a laptop but what other uses are there for tethering a phone or using the hotspot?

Then help some of your friends. They will use it.
