Nokia 3620 User Guide

							[ 42 ] Note: If you need to enter the Phone IP address, Primary name 
server, or Second name server, contact your Internet service provider 
to obtain these addresses.
The following settings are shown if you have selected data call and high-
speed data as the connection type:
Use callback—This option allows a server to call you back once you have 
made the initial call, so you have a connection without paying for the call. 
Contact your service provider to subscribe to this service.
Note: Charges may apply for certain types of received calls, such 
as roaming and high-speed data calls. Contact your GSM service 
provider for more information.
Note: The phone expects the callback call to use the same data call 
settings that were used in the callback-requesting call. The system 
must support this type of call in both directions, to and from 
the phone.
Callback type—The options are Use server no. / Use other no. Ask your 
service provider for the correct setting; it will depend on the service 
provider’s configuration.
Callback number—Key in your phone’s data phone number which the dial 
back server uses. Usually, this number is the data call phone number of 
your phone.
Use PPP compression—When set to Yes, this option speeds up the data 
transfer, if supported by the remote PPP server. If you have problems with 
establishing a connection, try setting this to No. Contact your service 
provider for guidance.
Note: PPP (Point-to-Point Protocol)—a common networking 
software protocol that enables any computer with a modem 
and a phone line to connect directly to the Internet.
Use login script—The options are Yes / No.
Login script—Insert the login script.
Modem initialization—(Modem initialization string)—Controls your phone 
using modem AT commands. If required, enter characters specified by your 
GSM system service provider or Internet service provider. 
						

							[ 43 ]Settings
GPRS
Go to Settings→ Connection settings→ GPRS.
The GPRS settings affect all access points using a packet data connection.
GPRS connection—If you select When available and you are in a system 
that supports packet data, the phone registers to the GPRS system and 
sending text messages will be done using GPRS. Also, starting an active 
packet data connection, for example, to send and receive e-mail, is quicker. 
If you select When needed, the phone will use a packet data connection 
only if you start an application or action that needs it. The GPRS connection 
is closed after it is not used by any application. 
Note: If there is no GPRS coverage and you have chosen When 
available, the phone will periodically try to establish a packet 
data connection.
Access point—The access point name is needed when you want to use 
your phone as a packet data modem to your computer.
Data call
Go to Settings→ Connection settings→ Data call.
The Data call settings affect all access points using a data call and 
high-speed data call.
Online time—If there are no actions the data call is dropped automatically 
after a time-out period. The options are User defined, in which case you 
enter a time, or Unlimited.
 DATE AND TIME
The date and time settings allow you to define the date and time used in 
your phone, as well as change the date and time format and separators. 
Choose Clock type→ Analog or Digital to change the clock shown in the 
standby mode. Choose Auto time update if you want the mobile phone 
system to update time, date, and time zone information to your phone 
(system service). 
For the Auto time update setting to take effect, the phone needs to 
be restarted.

 SECURITY
Phone and SIM
Explanations for the different security codes that may be needed:
PIN code (4 to 8 digits)—The PIN (Personal Identification Number) 
code protects your SIM card against unauthorized use. The PIN code 
is usually supplied with the SIM card. After three consecutive incorrect 
PIN code entries, the PIN code is blocked. If the PIN code is blocked, 
you need to unblock the PIN code before you can use the SIM card 
again. See the information about the PUK code.
PIN2 code (4 to 8 digits)—The PIN2 code, supplied with some SIM 
cards, is required to access some functions, such as call cost counters.
Lock code (5 digits)—The lock code can be used to lock the phone 
and keypad to avoid unauthorized use. 
Note: The factory setting for the lock code is 12345. To avoid 
unauthorized use of your phone, change the lock code. Keep the 
new code secret and in a safe place separate from your phone.
PUK and PUK2 codes (8 digits)—The PUK (Personal Unblocking Key) 
code is required to change a blocked PIN code. The PUK2 code is 
required to change a blocked PIN2 code. If the codes are not supplied 
with the SIM card, contact the operator whose SIM card is in your 
phone for the codes.
You can change the following codes: lock code, PIN code, and PIN2 code. 
These codes can only include the numbers from 0 to 9. 
Note: Avoid using access codes similar to the emergency numbers, 
such as 911, to prevent accidental dialing of the emergency number.
PIN code request—When the PIN code request is active, the code is 
requested each time the phone is switched on. Note that deactivating the 
PIN code request may not be allowed by some SIM cards.
PIN code / PIN2 code / Lock code—Open this setting if you want to change 
the code.
To lock the phone manually, press  . A list of commands opens. 
Select Lock phone. 
						

							[ 45 ]Settings
Autolock period—You can set an autolock period, a time-out after which 
the phone is automatically locked and can be used only if the correct lock 
code is entered. Key in a number for the time-out in minutes or select None 
to turn off the autolock period. To unlock the phone, key in the lock code.
Note: When the phone is locked, calls may be possible to the 
emergency number programed into your phone (e.g. 911 or other 
official emergency number).
Lock if SIM changed—Select Yes if you want the phone to ask for the lock 
code when an unknown, new SIM card is inserted into your phone. The phone 
maintains a list of SIM cards that are recognized as the owner’s cards.
Fixed dialing—You can restrict your outgoing calls to selected phone 
numbers, if supported by your SIM card. You need the PIN2 code for this 
function. When this function is active, you can only call those phone 
numbers that are included in the fixed dialing list or which begin with the 
same digit(s) as a phone number on the list.
To view the list of Fixed dialing numbers, go to Menu→ SIM→ Fixed dialing.
Options in the Fixed dialing view are: 
Open, Call, New contact, Edit, Delete, Add to Contacts, Add from Contacts, 
Help and Exit.
Note: When Fixed Dialing is set on, calls may be possible to certain 
emergency numbers programmed into your phone (911 or other 
official emergency numbers).
To add new numbers to the Fixed dialing list, select Options→ New contact 
or Add from Contacts. 
Closed user group (system service)—You can specify a group of people to 
whom you can call and who can call you. For more information, contact 
your service provider. Select Default to activate the default group agreed 
on with the service provider, On if you want to use another group (you need 
to know the group index number), or Off.
Note: When calls are limited to Closed User Groups, calls may be 
possible to certain emergency numbers programmed into your 
phone (911 or other official emergency numbers). 
						

							[ 46 ] Confirm SIM services (network service)—You can set the phone to display 
confirmation messages when you are using a SIM card service.
Certificate management
In the Certificate management main view, you can see a list of authority 
certificates that have been stored in your phone. To manage certificates, 
go to Menu→ Settings→ Security→ Certif. management. Press   to 
see a list of user certificates, if available.
Options in the certificate management main view are: 
Certificate details, Delete, Trust settings, Mark/Unmark, Help, and Exit.
Digital certificates are used to verify the origin of browser pages and 
installed software. However, they can only be trusted if the origin of 
the certificate is known to be authentic. 
Digital certificates are needed if you want to:
Connect to an online bank, another site, or remote server for actions 
that involve transferring confidential information.
Minimize the risk of viruses or other malicious software and be sure of 
the authenticity of software when downloading and installing software.
Authority certificates are used by some services, such as banking services, 
for checking signatures or server certificates or other authority certificates. 
User certificates are issued to users by a Certifying Authority.
Important: Although the use of certificates makes the risks involved 
in remote connections and software installation considerably smaller, 
they must be used correctly in order to benefit from increased security. 
The existence of a certificate does not offer any protection by itself; 
the certificate manager must contain correct, authentic, or trusted 
certificates for increased security to be available.
VIEWING CERTIFICATE DETAILS—CHECKING AUTHENTICITY
You can only be sure of the correct identity of a browser gateway or a 
server when the signature and the period of validity of a browser gateway 
or server certificate have been checked.  
						

							[ 47 ]Settings
You will be notified on the phone’s display: 
If the identity of the browser server or gateway is not authentic. 
If you do not have the correct security certificate in your phone. 
To check certificate details, scroll to a certificate and select Options→ 
Certificate details. When you open certificate details, Certificate 
management checks the validity of the certificate and one of the 
following notes may appear:
Certificate not trusted—You have not set any application to use the 
certificate. For more information, see “Change the trust settings of an 
authority certificate” on p. 47.
Expired certificate—The period of validity has ended for the 
selected certificate.
Certificate not valid yet—The period of validity has not yet begun for 
the selected certificate.
Certificate corrupted—The certificate cannot be used. Contact the 
certificate issuer.
Important: Certificates have a restricted lifetime. If Expired 
certificate or Certificate not valid yet is shown even if the certificate 
should be valid, check that the current date and time in your phone 
are correct.
CHANGE THE TRUST SETTINGS OF AN AUTHORITY CERTIFICATE
Scroll to an authority certificate and select Options→ Trust settings. 
Depending on the certificate, a list of the applications that can use the 
selected certificate is shown. For example:
Services / Yes—the certificate is able to certify sites. 
Application manager / Yes—the certificate is able to certify the origin of 
new software.
Internet / Yes—the certificate is able to certify e-mail and imaging servers. 
Important: Before changing these settings, you must make sure 
that you really trust the owner of the certificate and that the 
certificate really belongs to the listed owner.
