Java™
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
Sagemwireless 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
- Write User data
- Multimedia recording
Each of these security groups has one of 5 possible authorizations levels (listed from
the more restrictive to the more permissive):
- Never: The security group completely prevents access to the protected features.
