While charging, the device and the charger may heat up. This is normal and should not
affect the devices lifespan or performance. If the battery gets hotter than usual, the
charger may stop charging.
If you charge the device while the multipurpose jack is wet, the device may be damaged.
Thoroughly dry the multipurpose jack before charging the device.
If the device is not charging properly, take the device and the charger to a Samsung
Service Center.
SIM or USIM card (nano-SIM card)
Insert the SIM or USIM card provided by the mobile telephone service provider.
For dual SIM models, 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.
Some services that require a network connection may not be available depending on
the service provider.
