Java™
You are the owner of a SAGEM mobile phone which gives you the ability to download applications and games to be
executed on your phone thanks to the built-in Java™ engine.
However, receiving applications from everywhere implies some basic knowledge of the possible effects of such
download.
Thank you for spending a few minutes reading these pages: this will prevent you from performing action without
measuring the consequences.
Security considerations
Java™ MIDP technology is an efficient way to provide powerful applications in mobile phones. It allows use, by "over the air"
downloaded applications or games, of the great features built-in in a mobile phone (SMS sending and receiving, multimedia
playback and recording, network access…).
All these MIDP 2.0 features cannot be simply exposed to any MIDlet installed in the handset: a careful access control system
is implemented in the device to protect your private data and airtime consumption.
Access controls are gathered in 9 security groups:
- Network access (GPRS/GSM data airtime consumption, HTTP/web connections…)
- Auto invocation (MIDlet can wake up at a given time or when receiving a SMS)
- Phone call (ability to initiate a phone call)
WARNING: When running a Java™ application, you may be prompted to grant access to protected features. These
features are protected because using them could incur you cost, or involve your personal data. Read the security
popup message carefully, to understand what feature is requested, and decide whether it is legitimate for the
application to perform it. In case of doubt, don't hesitate to refuse access by selecting the "No" button!
The security configuration menu is an expert feature ! You must know exactly what you are doing before attempting
to change security parameters of a MIDlet. Misunderstanding changes may render MIDlet non functional
and/or lead to higher risks for your private data or impact your airtime consumption. Any changes in the
security configuration are done under your responsibility. In no case shall Sagem Communication and/or your
network provider be liable for any damages deriving from or arising out of such changes in the security
configuration.
You must be aware that applications downloaded to your phone could cause the phone to perform actions for which
you will be billed, like making calls and sending SMS. Depending on your operator's billing policy, you may also be
charged to download the application because of airtime consumption.
