Network services and costs
Using some features and services, or downloading content, including free items, require a network connection. This may cause the transfer of large amounts of data, which may result in data costs. You may also need to subscribe to some features.
You can only use your device on the GSM 900/1800 and WCDMA1 and 8 networks. You need a subscription with a service provider.
