Nextel comm I930 Benutzerhandbuch

• GSM preferred —This option is useful if your home system is GSM and you travel to 

a country or region where iDEN is also available. Your phone will always search for 
GSM networks first. If a GSM network is not found, your phone will then search for an 
iDEN network.

• iDEN only — This option is useful when you are in an area that is covered by iDEN 

and GSM networks, but you want to use iDEN. Your Smartphone attempts to register 
only on iDEN networks. This is the optimal setting you should set your Smartphone to 
when in a Nextel iDEN service region.

• GSM only — This option is useful when you are in an area that is covered by iDEN 

and GSM, but you want to use GSM. Your Smartphone attempts to register only on 
GSM networks. This is the optimal setting you should set your Smartphone to when in 
a region with only GSM carriers.

• Roam — This option is useful when you are in an overlapping system-coverage area 

and have no preference for either the iDEN or the GSM network. Your Smartphone will 
switch between iDEN and GSM until it finds an acceptable network.
Note: Be aware that some features that are supported by the Nextel iDEN network 

are not supported when you connect to a GSM network.

On the Home screen, select Start.

Select Settings and then Phone Networks.

Select iDEN/GSM Selection.

In iDEN/GSM selection, select to the option you want.

Select Done.

While you are on a GSM network, you can perform an automatic or manual search for 
available networks. A manual search allows you to view the available networks and 
make a selection rather than use the network automatically selected by the Nextel 
Worldwide Service.

Note: Your phone will automatically attempt to register with networks that have 

agreements with Nextel. By manually selecting a network, you may choose a 
network that does not have an agreement with Nextel or does not offer optimal 
coverage in that area.

On the Home screen, select Start.

Select Settings and then Phone Networks.
