Data roaming is the use of cellular data services on a mobile device outside of the coverage area of the home network. When a phone disconnects from its carriers network and hops on another network, it is considered roaming. Roaming allows you to make calls, send texts, and use wireless data even when youre outside of your networks boundaries. However, data roaming can result in additional charges from your mobile service provider, which can vary depending on the destination and the type of data usage. It is important to understand data roaming settings on your device and to manage usage to avoid unexpected charges. The term “data roaming” refers to any time your phone connects to the Internet on any network other than your home network. While roaming typically occurs while traveling, “home network” refers to your carrier’s coverage and not to a geographical location. Regardless of where you are, you won’t be roaming if your carrier has service in that area. To avoid unexpected data roaming or data plan charges on your mobile phone, you can disable the “data roaming” option using your device’s “Settings” menu.
