I'm running a laptop off my cell phone hot spot!

4. Keep an eye on your Data Usage

You don't want to get surprised with a huge bill. This will depend on what kind of contract you have with your cell service provider for your smartphone.

Data usage goes waaay up when you are viewing video/audio, and when you are connected with a laptop to your phone, all of that connection is using your cell data plan.

If you laptop decides to do major Windows updates, all that downloading will be added to your data bill. One way to avoid that is to make sure everything is as up to date as possible while you are connected to Wifi. You can also pause Microsoft Updates.

Just a few considerations. Other than that, yes, using your phone as a hotspot is great technology! Especially if you have good reception to cell towers. Mine is faster than my home wifi! (but I have no cell coverage at home, so I am not even tempted to use it when I'm not traveling).
