Dual Card Dual Standby Single Pass (dual-SIM devices only)

Your device supports only dual card dual standby single pass, which means you cannot use both SIM cards for calls or data services simultaneously.

When you are on a call using SIM card 1, SIM card 2 cannot be used to make or answer calls. If someone calls SIM card 2, the caller will hear a voice message similar to “The subscriber you dialed is out of the service area” or “The subscriber you dialed cannot be connected for the moment, please try again later.” The actual message will vary by service provider.
When you are using SIM card 1’s data service, SIM card 2’s data service will be disabled.
Your device’s single pass feature helps reduce power consumption and increase your device’s standby time. It is not related to your service provider’s network conditions.
You can go to Settings > Wireless & networks > Dual SIM settings, and enable Enable call forwarding between SIMs to avoid the conflicts mentioned above.

Safety Information

Please read all of the safety information carefully before using your device to ensure its safe and proper operation and to learn how to dispose of your device properly.

Operation and safety

To prevent possible hearing damage, do not listen at high volume levels for long periods.
Using an unapproved or incompatible power adapter, charger, or battery may damage your device, shorten its lifespan, or cause a fire, explosion, or other hazards.
Ideal operating temperatures are 0 °C to 35 °C. Ideal storage temperatures are -20 °C to +45 °C.
Pacemaker manufacturers recommend that a minimum distance of 15 cm be maintained between a device and a pacemaker to prevent potential interference with the pacemaker. If using a pacemaker, hold the device on the side opposite the pacemaker and do not carry the device in your front pocket.
Keep the device and the battery away from excessive heat and direct sunlight. Do not place them on or in heating devices, such as microwave ovens, stoves, or radiators.
Observe local laws and regulations while using the device.
To reduce the risk of accidents, do not use your wireless device while driving.
While flying in an aircraft or immediately before boarding, only use your device according to instructions provided. Use of a wireless device in an aircraft may disrupt wireless networks, present a hazard to aircraft operation, or be illegal.
To prevent damage to your device’s parts or internal circuits, do not use it in dusty, smoky, damp, or dirty environments or near magnetic fields.
When charging the device, make sure the power adapter is plugged into a socket near the devices and is easily accessible.
Unplug the charger from electrical outlets and the device when not in use.
Do not use, store or transport the device where flammables or explosives are stored (in a gas station, oil depot, or chemical plant, for example). Using your device in these environments increases the risk of explosion or fire.
Dispose of this device, the battery, and accessories according to local regulations. They should not be disposed of in normal household waste. Improper battery use may lead to fire, explosion, or other hazards.
Please consult your doctor and the device manufacturer to determine if operation of your phone may interfere with the operation of your medical device.
Adhere to any rules or regulations set forth by hospitals and health care facilities.
Potentially Explosive Atmosphere Power off your device in any area with a potentially explosive atmosphere, and comply with all signs and instructions. Areas that may have potentially explosive atmospheres include the areas where you would normally be advised to turn off your vehicle engine. Triggering of sparks in such areas could cause an explosion or a fire, resulting in bodily injuries or even deaths. Do not power on your device at refueling points such as service stations. Comply with restrictions on the use of radio equipment in fuel depots, storage, and distribution areas, and chemical plants. In addition, adhere to restrictions in areas where blasting operations are in progress. Before using the device, watch out for areas that have potentially explosive atmospheres that are often, but not always, clearly marked.
Such locations include areas below the deck on boats, chemical transfer or storage facilities, and areas where the air contains chemicals or particles such as grain, dust, or metal powders. Ask the manufacturers of vehicles using liquefied petroleum gas (such as propane or butane) whether this device can be safely used in their vicinity.
Disposal and recycling information

The crossed-out wheeled-bin symbol on your product, battery, literature or packaging reminds you that all electronic products and batteries must be taken to separate waste collection points at the end of their working lives; they must not be disposed of in the normal waste stream with household garbage. It is the responsibility of the user to dispose of the equipment using a designated collection point or service for

separate recycling of waste electrical and electronic equipment (WEEE) and batteries according to local laws.
Proper collection and recycling of your equipment helps ensure electrical and electronic equipment (EEE) waste is recycled in a manner that conserves valuable materials and protects human health and the environment, improper handling, accidental breakage, damage, and/or improper recycling at the end of its life may be harmful for health and environment.
