Define internet connections
If your network service provider charges you on a pay-as-you-use basis, you may want to
change the Wi-Fi and mobile data settings to reduce your data costs. You can use different
settings for roaming and at home.
Important: Use encryption to increase the security of your Wi-Fi connection. Using
encryption reduces the risk of others accessing your data.
Using a Wi-Fi connection is generally faster and less expensive than using a mobile data
connection. If both Wi-Fi and mobile data connections are available, your phone uses the Wi-
Fi connection.
