INSTRUCTIONS & INFO
CHECK NETWORK CONNECTION STRENGTH: When connected to 4G LTE, the 4G LTE icon will be displayed in the Notification bar. The Signal Bars display the connection strength. The more bars that are displayed, the better the connection.
TURN ON/OFF INTERNATIONAL DATA: From the Networks tab in Settings, select Mobile networks. Select International data roaming.
TURN ON/OFF INTERNATIONAL DATA & MOBILE DATA: Select the Mobile data switch to turn data roaming on or off.
