Network Connection
CHECK NETWORK CONNECTION AND STRENGTH:
• CONNECTION TYPE: When connected to 4G LTE, the LTE icon will be displayed in the Notification bar.
• CONNECTION STRENGTH: The Signal Bars display the connection strength. The more bars that are displayed, the better the connection.
1. ACCESS CELLULAR DATA: Swipe down from the Notification bar with two fingers, then select the 
Settings icon.
Note: Mobile data is on by default. Turning off the mobile data will not allow any data to be transferred over the wireless network. Wi-Fi access, voice function, and standard text messaging are still allowed. You can also turn data on/off using your myAT&T account. Learn more about disabling or activating AT&T Mobile Share member’s data usage by device.
