900 to 1800MHz
Not all 3G networks use 2100 MHz, only 3G in Japan and South Korea does. The higher you go in GSM, the more superior the results, which means a GSM 1800 is better than a GSM 900.

Hi, For every GSM band there are Uplink and downlink frequencies. Example: GSM 900 TX: 880 MHz to 915 MHz is an uplink frequency range GSM 900 RX: 925 MHz to 960 MHz is a downlink frequency range Aloha, Maverick
No, range of the phone is GSM 900/ 1800. GSM range in the US is 850/ 1900.
gsm 900 less base stations compared to 1800, gsm 1800 more capacity compared to 900 in terms of traffic hence less congestion.
GSM 900: Uplink frequency: 890 - 915 MHz GSM 1800 : Uplink frequency: 1710 - 1785 MHz GSM 1900: Uplink frequency: 1850 - 1910 MHz
