How do I select a network when
traveling?
In most cases, your BlackBerry® device automatically
roams to an appropriate network.
If you have a preferred network list, your device scans
first for networks in the list.
If your device continues to display a limited level of
wireless coverage, you can attempt to improve the
level of wireless coverage by selecting a different
network. To select a network manually, in the device
options, click
Network. Set the Selection Mode field
to Manual. Click Scan for Available Networks. In the
networks list, click a network. Click Select Network.
Your SIM card must be provisioned for roaming
services before you can select a different network.
Contact your service provider for more information
about roaming.
Notes:
Your device connects to the selected network and
remains connected to it until you select your home
network again, or until you select another network.
To reconnect to your home network, in the device
options, click
Network. Set the Network Selection
Mode field to Automatic.
How do I register my device with the
network?
When you select a different network or load new
programs, your BlackBerry® device should register
with the network automatically. To register your
device manually, in the device options, click
Advanced
Options. Click Host Routing Table. Click the
trackwheel. Click Register Now.
