6 Connecting to networks and devices
Your phone can connect to a variety of networks and devices, including mobile networks for voice and data
transmission, Wi-Fi data networks and Bluetooth devices, such as headsets. You can also connect your
phone to a computer, to transfer files from your phone and share your phone’s mobile data connection via
USB or as a portable Wi-Fi hotspot.
Connecting to mobile networks
When you assemble your phone with a SIM card from your wireless service provider, your phone is
configured to use your provider’s mobile networks for voice calls and for transmitting data. If your phone
does not connect to a network, contact your carrier for assistance. You may need to obtain the details of its
access point name (APN) or other details; see chapter “Edit or create a new GSM access point”.
The icons in the Status bar indicate which kind of data network you’re connected to and the voice and data
network signal strength. When you’re connected to slower networks, you may want to postpone using
your phone for data-intensive tasks until you are connected to a faster network again, or find a Wi-Fi
network to connect to. See “Connecting to Wi-Fi networks”.
Determine what GSM network you’re using
Press Settings to open the Settings application.
Touch Wireless & networks > Mobile networks > Dual SIM settings > select SIM > Access Point Names.
The name of the wireless service provider you’re currently registered with is selected in the list.
Disable data when roaming
You can prevent your phone from transmitting data over other carriers’ mobile networks when you leave
an area that is covered by your carrier’s networks. This is useful for controlling expenses if your cell plan
doesn’t include data roaming.
Press Settings to open the Settings application.
Touch Wireless & networks > Mobile networks > and uncheck Data roaming.
With Data roaming unchecked, you can still transmit data with a Wi-Fi connection. See “Connecting to
Wi-Fi networks”.
Edit or create a new GSM access point
If you and your GSM wireless service provider determine that you need to change the settings of your
current access point name (APN) or to create a new one, you must obtain the APN and detailed settings
from your provider.
Press Settings to open the Settings application.
Touch Wireless & networks > Mobile networks > Dual SIM settings > select SIM > Access Point Names.
