Does your network service provider charge you a fixed fee for data transfer or on a pay-as-you-use basis? Change the WiFi and mobile data settings to reduce your data costs while roaming and at home.

Important: Use encryption to increase the security of your WiFi connection. Using encryption reduces the risk of others accessing your data.
