Wi-Fi connection
Your device can detect and connect to wireless local area
networks (Wi-Fi). Using a Wi-Fi, you can connect your device
to the internet and compatible devices that have Wi-Fi
support.
About Wi-Fi
To use a Wi-Fi connection, it must be available in the location,
and your device must be connected to Wi-Fi. Some Wi-Fi
networks are protected, and you need an access key from the
service provider to connect to them.
Note: In France, you are only allowed to use Wi-Fi indoors.
Features that use Wi-Fi, or that are allowed to run in the
background while using other features, increase the demand
on battery power and reduce the battery life.
Important: Always enable one of the available encryption
methods to increase the security of your wireless LAN
connection. Using encryption reduces the risk of
unauthorized access to your data.
Wi-Fi connections
To use a wireless LAN (Wi-Fi) connection, you must create an
internet access point (IAP) for Wi-Fi. Use the access point for
applications that need to connect to the internet.
A Wi-Fi connection is established when you create a data
connection using a Wi-Fi internet access point. The active Wi-
Fi connection ends when you end the data connection.
You can use Wi-Fi during a voice call or when packet data is
active. You can only be connected to one Wi-Fi access point
device at a time, but several applications can use the same
internet access point.
When the device is in the offline profile, you can still use Wi-
Fi (if available). Remember to comply with any applicable
