SIM, USIM or UIM card (nano-SIM card)
Installing the SIM, USIM or UIM card
Insert the SIM, USIM or UIM card provided by the mobile telephone service provider.
You can insert two SIM, USIM or UIM 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, USIM or UIM card. Samsung is not
responsible for any damages or inconveniences caused by lost or stolen cards.
