Getting Started - NEC DB500 Manual

Getting Started

The DB500 is a dual band digital cellphone designed for use on a Global System for Mobile Communications (GSM) network. GSM networks
are installed and planned for many countries throughout Europe and operate on two frequencies: 900MHz (known as GSM900 or just GSM)
and 1800MHz (known as GSM1800 or PCN - Personal Communications Network). Your DB500 is capable of working on both of these
systems.
This world standard allows you to roam and use your own phone in other countries. You can, if you wish, make and receive all calls as if you
were in your home country, with all billing being made via your normal Service Provider.
Preparing the phone
Before you try to use your phone check the following has been carried out.
Valid SIM card inserted (see below)
l
Battery charged (see page 13)

PIN 1 code entered (if necessary - see page 2)

SIM card
Before using your cellphone you must sign-up with one of the digital network Service Providers. In addition to your subscription details you
will receive a personal SIM (Subscriber Identity Module) which is inserted into your phone.
If the SIM card is removed then the phone becomes unusable until a valid SIM is fitted. It is possible to transfer your SIM to another
compatible phone and resume your network subscription.
There are two types of SIM, plug-in and full-size, and this phone uses the plug-in type. The screen on your phone will display appropriate
messages if no SIM is fitted.
