Getting started
Using dual SIM or USIM cards (dual SIM models)
If you insert two SIM or USIM cards, you can have two phone numbers or service providers for a single device.

On the Home screen, tap 
→Settings →SIM card manager. Tap one or both of the switches for the SIM or USIM cards to activate them.
Changing the display name and icon of SIM or USIM cards
On the Home screen, tap 
→Settings →SIM card manager. Select a SIM or USIM card and tap Register name or Select icon. Set a display name and icon for each card.
Switching between cards
When two SIM or USIM cards are activated, card selection icons appear on the dashboard of the notifications panel. Open the notifications panel and then select a card.
Charging the battery
Use the charger to charge the battery before using it for the first time. A computer can be also used to charge the battery by connecting them via the USB cable.
Use only
•When the battery power is low, the battery icon appears empty.
•If the battery is completely discharged, the device cannot be turned on immediately when the charger is connected. Allow a depleted battery to charge for a few minutes before turning on the device.
•If you use multiple apps at once, network apps, or apps that need a connection to another device, the battery will drain quickly. To avoid disconnecting from the network or losing power during a data transfer, always use these apps after fully charging the battery.
