Can you tether a cell phone to laptop?
Yes, what kind of phone do you have?
You can get a USB modem that you get from cell phone companies. You can tether to you computer with your cell phone using a cable or bluetooth, but there are a few caveats to this. Also you can just go to a store like Starbucks (or many other places) where Wi-Fi is sometimes free. Or if you stay in a hotel sometimes you can connect with a CAT-5 Ethernet cable.
