Signal Strength Indicator
The signal strength of the Phone (voice only) WWAN connection is indicated by the number of bars that
appear in the status icon at the top of the window. The more bars shown, the stronger the signal. The
icon also provides information on the type of service connection.
SIM Card
In order for the terminal to access and work on some provider cellular networks, you may be required to
install an activated SIM card in the terminal. A SIM card (Subscriber Identity Module) stores information,
such as your subscriber profile, plan features, GSM/GPRS radio settings, security keys and your
contacts list. One of the advantages of using a SIM card is that it allows you switch to another compatible
mobile device without losing setup and personal information specific to the provider network.
On the Dolphin 99EX, the SIM card socket is located in the battery well under a protective door that is
secured with a T6 TORX screw. The socket is compatible with a standard size SIM card.
Before Installing a SIM Card
• The service provider must activate the SIM card or
associated service account prior to the installation.
• Always power down the terminal before attempting to
remove the battery and install a card.
Note: If no SIM card is installed, you can still make emergency phone calls
(e.g., 9-1-1).
Installing a SIM Card
1. Press the Power key to put the terminal in Suspend Mode.
2. Release the hand strap near the speaker on the back panel of
the terminal.
3. Remove the battery door.
