Roaming allows you to access a cell signal from another cell tower that does not belong to your network. If you ever wander out of your Boost Mobile coverage area, it is wise to enable your mobile phone to roam. Boost Mobile does not charge a fee if you so happen to roam outside of its network. Understanding how to enable the roam settings on your Boost Mobile phone is simple.
Press the "Home" button on your Boost Mobile phone and select the option "Settings."
Scroll down the settings menu and select "Roaming."
Select the option to "Enable" roaming on your Boost Mobile phone.
Select "Save" and press the "Home" key to return to the main menu.
