Getting started

Nano-SIM card
Insert the SIM or USIM card provided by your carrier.
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 carrier.
