Nokia 5170i manual System selection, Service Types, Roaming

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.
