When running a Java™ application, you may be prompted to grant
access to protected features. These features are protected because
using them could incur a cost, or involve your personal data. 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 the
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 Mobiles 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, such as 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.
Security considerations
Java™ MIDP technology is an efficient way to provide powerful
applications in mobile phones.
All these MIDP 2.0 features cannot be displayed on MIDlet installed
in the handset: an advanced access control system is implemented
in the device to protect your private data and airtime consumption.
Access controls are collected in 9 security groups:
- Network access
- Auto invocation
- Phone call
- Local connectivity
- Messaging receive
- Messaging sending
- Read User data
