How to connect to the internet with a laptop and a cell phone

Can your phone act as a Personal Hotspot? Major carriers will charge extra to allow a phone used on their system as a hotspot (and probably won't provide extra data) but, that would be the easiest way. Modern smartphones are usually easy to set up as a Personal Hotspot and, once set up, you can usually connect multiple devices via your WiFi network. Do set up encryption.
