You could use that to place a VOIP call via the internet, without using your phone to actually dial the number to make the call. As far as I know, if you have no minutes on your phone, having a hotspot would not allow you to call from that phone, you still have no minutes on the phone.

Your smartphone costs a fortune in monthly fees. But there are new ways to get unlimited voice calling and significantly decrease the number of cell voice minutes you need. So pull out your smartphone, and we’ll fire up a few tools to potentially save you hundreds of dollars on your cell phone bill this year.

Wi-Fi Calling on Cell Phones Explained
Your cell phone can communicate in four distinct ways: voice calls, texts, data over cell networks, and data over Wi-Fi. What many people don’t realize is that connecting via Wi-Fi doesn’t count at all against your cell phone bill. So how can you exploit this loophole to cut down on your overall cell phone bill?

Making voice calls on you computer over the Internet is nothing new; but you can now combine your cell phone with Wi-Fi to make calls for free on your mobile devices. This could enable you to talk over Wi-Fi and downgrade your cell service to the cheapest plan available – one with fewer voice minutes than you’re currently paying for.
