At a glance
Let’s get started. We’ll guide you through startup and tell you where to find more information about your phone and its great features.
Set up your SIM card
The SIM (Subscriber Identity Module) card identifies your device to the wireless network. You can’t make or receive phone calls without a properly installed SIM card unless it’s an emergency call (911).
You don’t need to power off your device before inserting or removing the SIM card.
Note: Your device only supports Nano SIM cards. To avoid damage to your device, do not attempt to insert any other SIM types.
Insert the SIM pin that’s provided to eject the SIM tray and then slide it out gently.
Place or remove the Nano SIM card and the microSD card in the correct slot as shown.
Note: MicroSD cards are sold separately. SIM pin is included in the box.
Battery
To optimize battery performance, be sure to fully charge your device before using it for the first time.
Charging the device
- Insert the USB Type-C cable into the charge port as shown.
- Connect charger to power outlet.
Note: Please use the charger and USB Type-C cable that’s included with your device. Using the wrong cable and charger may damage the charging port or reduce battery performance.
Optimize battery life
To optimize battery life, adjust your screen brightness and display timeout.
- Adjusting brightness level: Lowering your screen brightness level can optimize your battery level. To adjust the brightness level, from the Home screen, touch Settings > Display > Brightness level. To lower the brightness level, move the wheel to the left.
- Power saving mode: Power saving mode minimizes battery usage to extend battery life. To explore power management options, from the Home screen, touch Settings > Smart Manager > Battery > Battery detail > Battery saver. Then touch TURN ON NOW to activate power saving mode.
- Adjust screen timeout: Sleep mode is a low power mode function and it significantly saves your battery power. Lower the amount of time your device stays on after you stop using it to optimize your battery level. To do so, from the Home screen, touch Settings > Display > Display > Sleep and select screen timeout duration.

Information about safeguarding handsets
We encourage customers to take appropriate measures to secure their devices and invite them to take advantage of the features available on this device to help secure it from theft and/ or other unauthorized access and use. This device has a locking function (e.g., Security PINs) that can serve as a first line of defense against unauthorized use or access to stored information. Preloaded security applications that allow customers to track or locate misplaced devices can be found on several devices. Lost or stolen devices should be immediately reported to your wireless carrier so that proper measures can be taken to protect accounts. For additional information, visit your wireless carrier’s Privacy Policy.
Emergency call
If your phone has network coverage, dial the emergency number and touch to make an emergency call. This works even without a SIM card and without typing the PIN code.
Although all phones are equipped with 9-1-1 emergency calling, this phone may or may not permit its location to be approximated during a 9-1-1 call. Be prepared to report your location when dialing 911*.
Availability of this feature depends on upgrades to the (a) wireless network and (b) 9-1-1 calling system that are required to be installed by the local 9-1-1 response agency or public safety answering point (PSAP); these upgrades may not be available everywhere within our wireless coverage area or your roaming area. This approximation of the phone’s location and the transmittal of location information are subject to emergency situations, transmission limits, network problems/limitations, interconnecting carrier problems, your phone, buildings/tunnels, signal strength and atmospheric/ topographical conditions, and may be curtailed, interrupted, dropped, or refused. The phone’s approximate location is transmitted to the local 9-1-1 response agency or PSAP while the call is in progress; this approximation is intended solely to aid the PSAP in dispatching emergency assistance or to limit the search area for emergency services personnel. You should not rely solely on a mobile phone for essential communications (such as a medical or other emergency). Please see your wireless carrier’s Terms and Conditions, and Privacy Policy for additional service restrictions and details.
