G.1.2.2 Shutting Down the Wireless WAN User Interface
While it is not usual to shut down the GSM/GPRS user interface, you can accomplish this by tapping on the
File menu and choosing the Exit command at the bottom of the main Wireless WAN dialog box.
G.1.3 Advanced Information
In most cases, when a GSM/GPRS radio and SIM are installed in your computer, setup is automatic. Follow
the steps outlined under the heading “Establishing a Packet Data Connection” on page G-3 to make a con-
nection. The information in this section is for advanced setup purposes.
G.1.3.1 Entering a PIN Number
If a PIN is required, a PIN entry dialog box is displayed.
• Type your PIN, and press [Enter] .
Once the correct PIN or PUK is entered or if none was required, the modem is instructed to perform a GSM
network registration followed by a GPRS attach. The main
Wireless WAN dialog box reflects the progress of
the initialization.
• Searching for modem.
• Initializing modem.
• SIM is ready.
• Searching for network.
• Registered on network.
• Searching for GPRS.
• Ready to connect.
If the modem loses the connection to the GSM network, the following states are repeated: Searching for
network , Registered on network , Searching for packet data , and Ready to connect .
G.1.3.2 Error States
The following temporary error states (i.e., these states may disappear without interaction) may be dis-
played:
• Emergency calls only.
The modem has found a network but is not allowed to register (e.g. no roaming agreement between
networks). The modem keeps searching for another network.
• No network found.
A network is not currently available. The modem continues searching for a network.
• Packet data not available.
The current network does not support a packet data service.
• Packet data not allowed.
The modem is not allowed to use the packet data service on the current network (e.g. no GPRS
roaming agreement between network; a roaming agreement for voice may still be in place). It is also
possible that you do not have a subscription for GPRS at all.
The remaining error states are permanent:
• SIM is missing.
The SIM card is missing. After the SIM has been inserted a warm boot may be required.
• SIM failure.
The SIM card is permanently disabled (e.g. because the wrong PUK has been entered too many times).
A new SIM is needed.
• Modem failure.
Note: Once you’ve shut down the user interface, you can only enable the radio by opening the Con-
trol Panel and tapping on the Wireless WAN icon to display the Wireless WAN dialog box.
Note: If you exceed the number of allowable attempts, a PUK entry window is brought to the fore-
ground. You’ll need to enter a new PIN number.
