Using the Device
3.3.2 Making/Receiving Calls
After you activate your SIM card(s), the GT78-VN 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.
To use the device for phone service, it is suggested that you connect a wired
headset to the device's headset connector or use a wireless Blueooth headset or
car kt. For instructions on how to connect to a Bluetooth device, see 3.5 Enabling
Bluetooth and Pairing with Bluetooth Device on page 31.
3.3.3 Data Connection
Connecting to a cellular network enables you to use voice service as well as
data connection service, e.g., the Internet connection. However, in most cases
using Wi-Fi for data connection is faster and less expensive than using a cellular
network and you may want to disable data connection of your SIM card when
Wi-Fi is available. On the other hand, you may want to enable cellular data
connection when Wi-Fi is not available.
To enable or disable data connection:
1. Swipe down the Status bar and tap
Mobile data .
1. Enable data connection for a desired
SIM card or tap Off to disable data
connection.
