BlackBerry Tour runs on the carrier's respective EV-DO Rev. A 3G networks domestically and offers 3G UMTS/HSPA (2100Mhz) and quad-band (GSM 850/900/1800/1900; GPRS/EDGE) support, so you can get voice and data coverage while traveling outside of North America. The smartphone also offers Bluetooth 2.0 (including stereo Bluetooth and tethering) as well as assisted and autonomous GPS, but unfortunately, there is no Wi-Fi.
