SUPER ROBUST USER MANUAL
SIM card information
When you subscribe to a cellular network, you receive a plug-in SIM
(Subscriber Identity Module) card loaded with your subscription details,
such as your PIN, and available optional services.
Be careful to handle, insert or remove the SIM card since the SIM card
and the contacts inside can easily be damaged by scratching or
bending.
Note
：
Before installing/removing the SIM card,
always make sure that the phone is switched off.
Installing the SIM card
Insert the SIM cards into their respective slots. Make sure that the
contact area on the cards is facing the connectors on the device.
Access codes
There are access codes for your SIM card. These codes help you to
protect the phone against unauthorized use.
When requested for any of the code explained below, key-in the
appropriate code (displayed as asterisks) and press the OK key.
PIN
The Personal Identification Number or PIN (4-8digits) protects your
SIM card against unauthorized use. The PIN comes with the SIM card;
see the SIM card instruction provided with your card.
If you enter an incorrect PIN three times in succession, the code will be
disabled and cannot be used until you re-enable it by entering the PUK.
PUK
The 8-digit PUK (Personal Unblocking Key) is required to change a
disabled PIN. The PUK may be supplied with the SIM card. If not, or in
case you have lost it, please contact your service provider.
To re-enable your PIN, proceed as follows.
1. Key-in the PUK and press the OK key.
2. Enter a new PIN of your choice and press the OK key.
3. When the Confirm New PIN message is displayed, key-in the
same code again and press the
OK key.
If you enter an incorrect PUK ten times in succession, the SIM card
becomes invalid. Please contact your service provider for a new card.
