SIM AT Service
SIM Card provides several value-added services.
These functions will only display and work on the menu of the
phone when your SIM card is supported. If your SIM Card
does not support such services, the phone will not display
those menus.
The content and the terms of the function lists will depend on
your network service provider.
Please contact your network service provider (a network
operator or the service provider) in regards with availability of
any services related to the SIM card, application information
and the costs.
Note:
Please be aware that charges may be applied to your bill
due to activated SMS or Call when you perform those
services. The text of SIM AT menus may be different from
your phone language setting because the text directly
comes from your SIM card
