The Nokia 20 GSM Connectivity Terminal requires:

• an RS-232 data connector

• AT Hayes command support

■

The Nokia 20 GSM Connectivity Terminal is approved for use in the GSM 900 and GSM 1800 networks 
and in the GSM 900/1800 dual band network.

The Nokia 20 GSM Connectivity Terminal supports High Speed Circuit Switched Data (HSCSD), which 
enables data transmission rates of up to 43.2 kbps. HSCSD makes downloading large files faster and 
more convenient.

Some of the features supported by the Nokia 20 GSM Connectivity Terminal are called network 
services. They are special services provided by wireless service providers. Before you can take 
advantage of any of these network services, you must subscribe to these service(s) from your home 
service provider and obtain instructions for their use. Services that need to be subscribed to are 
typically data service and fax service.

Some service providers may not provide all communications services. Contact your service provider for 
further information about the availability and details of the services in your home network. 

To access the Internet, you must have subscribed to the data service from your service provider and 
obtained an Internet access point from an Internet service provider.

Note that dual band functionality and HSCSD are network-dependent features. Check with your local 
service provider if you can subscribe to them.
