what is tethering data

Tethering is a way of sharing your phones mobile data connection with another device, such as a tablet or laptop, so that it can access the internet. It can be done by creating a small localized wireless internet connection, also known as a mobile hotspot, or by connecting the devices with a USB cable. Tethering can be useful when there is no Wi-Fi available, or when Wi-Fi costs extra to use, such as in hotels. Most Android phones can share mobile data by Wi-Fi, Bluetooth, or USB. However, some mobile carriers limit or charge extra for tethering, so it is recommended to check with your carrier. Tethering uses more data than browsing the web and using internet services on your phone, so it is important to consider the data allowance on your mobile contract. Some carriers charge an extra fee for tethering, while others dont, and it may cause you to run out of your monthly data allocation sooner than expected.
