You can also enbale the band configuration Tab to select manually an option: The page can be enabled with key sequence or registry key: [HKEY_LOCAL_MACHINE\Software\Symbol\PhoneSettingsEx\PH8\Band Page] Enable = DWORD:1 Definition: Enable  DWORD:1 Disable  DWORD:0 Next, on the phone go to Menu -> Options}

setting it with reg above will persist the parameters on the GSM module which likely not what we would recommend . as far i know we recommend using the below [HKEY_LOCAL_MACHINE\Software\Microsoft\RIL] “Selection2G3G” =dword:1 Possible values: 1 – Device will automatically select the network (default) 2 – Device will operate in GSM only (2G) 3 – Device will operate in UMTS only (3G)

Thank you guys for the quick responses. I managed to change the setting with your guidance. Best regards, Alex.

As per a previous posting from Herbert de Jong...
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\NETWORKSELECT]

"Sysid"=dword:x

Network type and GSM/UMTS Preferred values.

1: CDMA_ONLY,

2: GSM/UMTS_ONLY & Auto(GSM/UMTS),          (  default in EMEA GSM networks )

3: GSM/UMTS_ONLY & UMTS_ONLY,                ( 3G only )

4: GSM/UMTS_ONLY & GSM_ONLY,                 ( 2G only )

5: CDMA_first & Auto(GSM/UMTS),

6: GSM/UMTS_First & Auto(GSM/UMTS),          

7: CDMA_first & GSM_ONLY,

8: CDMA_first & UMTS_ONLY,

9: GSM/UMTS_First & GSM_Only,

10: GSM/UMTS_First & UMTS_Only, note: GSM/UMTS only means no CDMA will be tried. GSM/UMTS_First will try CDMA for US carriers.

Phone Network Setup applet will run at boot and if it finds a Simcard and GSM network it will choose value 2 automatically.
