While charging, the device and the charger may heat up. This is normal and should not
affect the device’s lifespan or performance. If the battery gets hotter than usual, the
charger may stop charging. If this occurs during wireless charging, disconnect the device
from the charger to let it cool down, then charge the device again later.
•
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 Centre.
Nano-SIM card and eSIM
Insert the SIM or USIM card provided by the mobile telephone service provider.
To have two phone numbers or service providers for a single device, activate the eSIM or
insert two SIM cards. Differing from a physical nano-SIM card, an eSIM is an embedded digital
SIM. Using both the nano-SIM card and the eSIM may result in slower data transfer speeds in
some areas.
•
eSIM may not be available depending on the region, service provider, or model.
•
Some services that require a network connection may not be available depending on
the service provider.
