SIM or USIM card (nano-SIM card) (SM-T577U/
DS)
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 only a nano-SIM card.
•
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 services that require a network connection may not be available depending on
the service provider.
