Using the Rugged Handheld Device
3.3 Using Cellular Network
After you insert the SIM card(s) to the GT-500 for the first time and power on
the GT-500, depending on your mobile network carrier you might be guided to
activate the account and connect to your mobile network. If you are asked for a
PIN to unlock the SIM card when powering on the GT-500, contact your cellular
network carrier for the default PIN.
Note:
The device comes with two SIM card slots, each with their own
supported networks. SIM card slot 1 supports 2G, 3G and 4G while slot 2
supports only 2G network. See 2.1 Installing microSD and SIM Card on page
10 for details.
When a new SIM card is detected by the GT-500, you will be prompted to
configure its usage, including voice call, messaging and data connection. You
can configure it now or change the settings later.
Featuring dual-SIM card slots, the GT-500 supports dual-SIM mobile
connection, allowing you to enjoy constant and seamless Internet connection.
Two cellular network icons will be displayed in the Notification Area to indicate
the connectivity and signal strength.
Different locations may have different mobile networks available. The GT-500
adopts the fastest mobile network available for data. However, in order to
extend the battery life, you can configure the GT-500 to use only a slower 2G
network for data. You can also configure the GT-500 to access a different set of
networks entirely, or to behave in special ways when roaming.
3.3.1 Making/Receiving Calls
After you activate your SIM card(s), the GT-500 auto-connects to your cellular
network when it powers on. You can start to use the phone service.
Using phone service, e.g., making or answering a call, is similar to the way you
use a mobile phone.
