Device management enables the remote distribution of 
settings for your phone, for example Internet, email, 
SMS and MMS. It also makes it possible to manage (list, 
install, update and uninstall) themes and client software 
on the phones. Device management is useful if an 
enterprise has, for example, defined a set of standard 
software that should be used on all employees’ phones.

To enter the settings or manage software in the phone, a 
device management session is setup between the phone 
and a device management server. The session can be 
initiated from the phone by you or from the server. 

Select 

. The device management server profiles, 

if any, are listed. The profiles settings describe how the 
profile will handle the start of a Device management 
session and the notifications given during the session. In 
the device management dialog you can:

•

Initiate the phone management session by 
highlighting a profile and selecting 

.

•

Create a new device management server profile 
manually by selecting 

.

•

Initiate reconfiguration for a new operator by 
selecting 

. This might be necessary if 

your phone is already configured for another 
operator.

•

Edit or delete device management server profiles.

Note: A profile may be locked by the operator. If it is, 
you cannot edit or delete the profile or clear ACL.

The device management dialog consists of two tabs, the 

 tab and the

 tab you 

edit details for the connection, like user name for the
