Important: Use standard
micro UIM and
micro SIM cards only. Inserting a smaller size card (such as a nano UIM/SIM with an adapter or a modified UIM/SIM) may cause the card to not fit properly or damage the card slot.
Take the back cover off.
In the slot 1, insert a CDMA
micro UIM or 3G/GSM
micro SIM card. In the slot 2, insert a GSM
micro SIM card.
When inserting, make sure the card’s gold contacts are facing down and its cut-off corner facing in.
