5 Insert the SIM or the R-UIM card into the cardholder.
Before inserting the SIM/R-UIM card, position it as shown in Figure 18, with the
card’s gold contacts facing the compartment. The cardholder connector base has
a set of contacts and a notch to ensure the SIM/R-UIM card is positioned correctly.
The SIM/R-UIM card has a notch on one corner to ensure that it fits into the
connector base in only one way.
NOTE
There is only one SIM/R-UIM slot and one SD slot (VX 680 3G has dual SIM
support, see Figure 19). Make sure you insert the SIM/R-UIM card into the SIM
slot, as shown in Figure 18.
