S S IM Card Protection
You can lock and unlock each SIM card that you use in your device with a PIN
(Personal Identification Number). When a SIM card is locked, the subscription
linked to the card is protected against misuse, meaning you have to enter a PIN
every time you start your device.
If you enter the PIN incorrectly too many times, your SIM card will get blocked. You
then need to enter your PUK (Personal Unblocking Key) and a new PIN. Your PIN
and PUK are supplied by your service provider.

Using Multiple SIM Cards

Your device works with either one or two SIM cards inserted. You get incoming
communication to both SIM cards and you can select which number you want to
place outgoing communication from. Before you can use both SIM cards, you need
to enable them and select which SIM card will handle data traffic.
You can 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
To enable or disable the use of two SIM cards

2 Tap the SIM1 and SIM2 sliders to enable or disable the SIM cards.
To rename a SIM card
