Unfortunately it's only going to support 900/1800/1900 and WCDMA 2100mhz
"The Nokia N93i is far more than just a digital camcorder - work or play, it delivers just what you need. Designed to work on WLAN, 3G (WCDMA 2100 MHz), EDGE and GSM (900/1800/1900 MHz) networks, the Nokia N93i provides mobile broadband internet access for browsing, uploading content, and sending and receiving emails, allowing you to stay connected on the move. You can also keep yourself entertained with MP3 music, podcasts, stereo FM radio or mobile TV video streaming**."
