Important information
For an optimal experience, the phone regularly connects
to mail and internet servers.
This automatically and inevitably generates data
exchanges that may be charged in addition to your
existing package, or may be deducted from prepaid
credit or a prepaid system.
To avoid billing problems related to services that use the
Internet, it is strongly recommended to have a suitable
option which includes unlimited Internet and emails and
to avoid changing the settings preconfigured by default.
If you wish, connect to Wi-Fi for a faster and more stream
lined experience. It is particularly recommended to use
Wi-Fi for streaming, or downloading games, videos or
large films.
