Multiple Networks

Standard voice and slow (2G) data network:

If you are using a mix of UK networks, then you will need a dual band repeater. A dual band 900/1800MHz repeater covers all UK networks (except 3 - see below).

High speed data network (3G):

All UK networks use the 2100MHz frequency for their 3G data service. Also the network 3 uses the 2100 MHz frequency for it's entire network.
