Using multiple SIM cards
Your device works with one or two SIM cards inserted. You get incoming
communication to both SIM cards and you can select from which number you want
to place outgoing communication. Before you can use both SIM cards, you need to
enable the SIM cards in the settings menu of your device. If both SIM cards are
locked with a PIN code when you turn on your device, you can choose to only unlock
and use one SIM card. In other words, you can bypass one locked SIM card.
You can also forward calls that come in on SIM card 1 to SIM card 2 when SIM card
1 is unreachable, and vice versa. This function is called Dual SIM reachability. You
must enable it manually. See
Forwarding calls on page 66 .
