Thumbs up Fujitsu LOOX F-07c

Hi, I just bought a Fujitsu LOOX F-07c. I like it, but, I'm having trouble putting music under Symbian. If you know about the phone, then you know it dual boots Symbian/Windows 7. The problem is when I access mtp mode, it gives me a message "Insert/Recheck UIM". I'd really hate to have to buy some type of service plan just to listen to music under Symbian, as for windows mode, it's pretty demanding, so it's hard to listen to music without an extended battery/charger which is difficult when your traveling in the case of the later. Any, help will be deeply appreciated.
