In some cases, when you try to connect to your service provider,
the following message may appear on the screen:
‘LOCK’ prevents the service provider from changing your
carrier lock code. ‘UNLOCK’ allows the provider to change
the code and restrict others from activating your phone.
If this happens, select the appropriate selection for your phone.
If you don’t want your service provider to change your lock
code, select
LOCK
. If you want to allow your service provider
to change your code to prevent other service providers from
activating your phone, press
UNLOCK
.
Press and hold for several seconds to return to the
start screen.
Note: Contact your service provider if you have any questions.
System selection
The System menu (
Menu
5) allows you to modify how your
phone will work when you are outside of your primary or
“home” system. (Items on the System menu may differ
depending on your service provider.) How your phone will
handle being out of your home area can significantly affect
the types and amounts of additional charges you may incur.
Service Types
In each wireless service area there are usually two service
providers, referred to as type
A
and type
B
.
When you first set up your wireless service account, your
service provider will inform you of which system you will
be using (for example, type
A
). This is your home system.
The other system (for example, type
B
) is known as your
non-home system.
Roaming
Roaming is a term used to indicate that your phone is not in
its home area. While roaming, you are actually using another
service provider’s system. Calls made or received while roaming
are usually more expensive than calls made in your home area.
