GPRS GPRS (general packet radio service) is a network service that allows mobile phones to be used for sending and receiving data over an IP-based network. GPRS is a data bearer that enables wireless access to data networks, such as the mobile Internet. Nokia 6620 User Guide 61 Copyright © 2004 Nokia Note: The Nokia 6620 phone is capable of using an EGPRS (enhanced GPRS) network connection. EGPRS is also known as EDGE (enhanced data rates for global evolution) and is similar to GPRS, but the connection is faster. For more information on availability of EGPRS and data transfer speed, contact your service provider. The applications that may use GPRS are multimedia, text messaging, streaming, browsing sessions, e-mail, data sync, Java™ application downloading, and the PC dial-up (such as Internet and e-mail). To use GPRS technology, you must first do the following: • Contact your service provider for availability and subscription to the GPRS service. • Save the GPRS settings for each of the applications used over GPRS. For information on pricing, contact your service provider. When you select GPRS as a data bearer, the phone uses EGPRS instead of GPRS, if this is available in the network. You cannot select between EGPRS and GPRS, but for some applications you may be able to select either GPRS or GSM data (CSD). To define GPRS connection settings, select Menu > Settings > Connection > GPRS, and the following: GPRS connection—If you select When available and you are in a network that supports packet data, the phone registers to the GPRS network. 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 can be closed after it is not used by any application. 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. See "Use your phone as a modem" on page 102. Data call Online time—This setting affects all access points using a data call. If there are no actions, the data call is dropped automatically after a time-out period. Select User defined (in which case you enter a time) or Unlimited. Configurations When you open a message that contains configuration settings for your phone, the message is displayed in this viewer. If you do not have any configuration settings messages, this screen will be empty. To delete a message from this screen, press the Clear key. Options in the configurations viewer are Save, Message details, and Move to folder. 62 Copyright © 2004 Nokia Settings • DATE AND TIME Select Menu > Settings > 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. Clock type—Select Analog or Digital to change how the clock is displayed in the standby mode. See "Clock" on page 81. Clock alarm tone—Changes the tone played when the clock reaches an alarm time. Auto time update—Allows the network to update time, date, and time zone information to your phone (network service). For the auto time update setting to take effect, the phone needs to be restarted. Check any alarms because they may be affected by the auto time update. GMT offset—Changes the time zone for the clock time. Daylight-saving—Sets daylight saving time on or off. • SECURITY Select Menu > Settings > Security > Phone and SIM or Certif. management. Phone and SIM If your phone requests a security code, refer to the following explanations to determine what you should enter. If you forget or lose a PIN or PUK code or if you have not received such a code, contact your service provider. You can change the following codes: lock code, PIN code, and PIN2 code. These codes can only include the numbers from 0 to 9. 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 your service provider for the codes. The PUK and PUK2 codes are 8 digits long. Avoid using security codes similar to 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 (4 to 8 digits)—The PIN 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 also the information below about the PUK code. PIN2 code (4 to 8...
