The above program will update your modem dashboard to the latest version and unlock your modem. It replaces the '3' dashboard.
----------------------------------------------
You will need to run the Mobile Partner setup program from your modem to install the new dashboard on your laptop.
Your new dashboard is the Mobile Partner software.
To set up a connection in Mobile Partner go to:
Tools > Options > Profile Management
Click New
Enter a profile name
The Settings for the '3' network are:
APN static
APN: three.co.uk
Access number: *98#
No username or password required leave blank
Click save
If you use a different networks simcard you will have to create a profile for that particular network using the correct settings for that network.
