SIM Card PIN protection 4.5

4.5 SIM Card PIN protection

If a SIM card is PIN-protected and the PIN is not programmed in EasyGate, GSM LED

indicates the state and the PIN tone is transmitted on telephone line.

PIN Entering by PCManager

Like other parameters, the PIN code can be entered using a PC programming tool. The

PIN will be entered automatically upon next EasyGate power up.

PIN Entering via Telephone Line

To enter the PIN via a telephone line using the DTMF:

1. Hook off the telephone, you can hear the PIN tone.

2. Enter the PIN using the DTMF; to cancel the wrong PIN hang up before

sending a

3. To confirm enter a

4. If you hear the busy tone in a while (a few seconds), you have entered the

PIN correctly. Hook on and wait for registering to the GSM network.

5. If you hear the PIN tone again in a while, you have entered a wrong PIN. Re-

enter the PIN.

6. If you hear the PUK tone in a while, you have entered a wrong PIN and the

SIM card is blocked. Use the mobile phone to unblock the SIM card.

A correctly entered PIN is stored in EasyGate’s memory as if you had programmed it

using the PCManager. The PIN will be entered automatically upon the next EasyGate

power up.

Automatic PIN Entering

You need not enter the PIN upon power up if it is stored in EasyGate – it is entered

automatically. This function is convenient in case of power failure; EasyGate is

operable in a short time after power recovery without any intervention by the

operating staff.

Warning

 One PIN entering option is exhausted by the attempt to enter the PN

automatically upon SIM card or PIN change. If wrong, the automatically

entered PIN is cleared from the internal memory to avoid another false

attempt upon next power on. There are still two manual PIN-entering

attempts after such unsuccessful automatic entering. To prevent the

unsuccessful automatic PIN entering, delete or program properly the

EasyGate PIN using the PCManager in the case of SIM card change.
