The Nokia N900 can be used on the Orange, T-Mobile and 3 (roaming on T-Mobile) networks which use the 1800 MHz frequency-band for GSM/GPRS/EDGE (2G) and on the O2 and Vodafone networks which use the 900 and 1800 MHz for 2G. All the previously listed providers and 3 use the 2100 MHz (WCMDA) frequency-band for 3G.[14] Virtual operators, such as Virgin Mobile, will connect on one of the network suppliers (T-Mobile or Vodafone) for network coverage.[15]
