Have you ever had the desire to share the Wi-Fi connection of your iPhone with an iPad or Mac nearby ? Lets say you do stay professional with your iPhone and MacBook in your luggage. You have two options : either work on your MacBook and do not have access to the internet, or have access to, but work on the small screen of your iPhone. If none of these two options you like, then choose the third : to use the Wi-Fi of your iPhone to work on your computer or tablet. Before anything else, it is recommended to check with your carrier or refer to the terms and conditions of your contract to know what you might.
