How the Master Switch and Roaming Interact

Understanding how your device handles network switches prevents accidental bill shock. The master cellular data switch turns off all mobile internet access globally, whether you are on your home network or a partner network. Meanwhile, the data roaming switch specifically controls whether your phone is allowed to use mobile data when connected to a foreign carrier outside your home coverage area. If you turn off the master cellular data switch, your phone cannot use any cellular data at all, meaning data roaming cannot function either.
