Precautions for wireless charging
•
Do not place the device on the wireless charger with a credit card or radio-
frequency identification (RFID) card (such as a transportation card or a key card)
placed between the back of the device and the device cover.
•
Do not place the device on the wireless charger when conductive materials, such
as metal objects and magnets, are placed between the device and the wireless
charger.
The device may not charge properly or may overheat, or the device and the cards
may be damaged.
•
If you use the wireless charger in areas with weak network signals, you may lose
network reception.
•
Use Samsung-approved wireless chargers. If you use other wireless chargers, the
battery may not charge properly.
SIM or USIM card (nano-SIM card)
Installing the SIM or USIM card
Insert the SIM or USIM card provided by the mobile telephone service provider.
You can insert two SIM or USIM cards so you can have two phone numbers or service
providers for a single device. In some areas, data transfer speeds may be slower if two SIM
cards are inserted in the device than when one SIM card is inserted.
Use caution not to lose or let others use the SIM or USIM card. Samsung is not
responsible for any damages or inconveniences caused by lost or stolen cards.
Some LTE services may not be available depending on the service provider. For more
information about service availability, contact your service provider.
