To determine compatible networks the customer will need to verify the compatibility of the frequency band from their handset and desired network.
GSM networks operate in a number of different carrier frequency ranges with most 2G GSM networks operating in the 900 MHz or 1800 MHz bands and 3G networks 850 MHz and 1900 MHz bands. In rare cases the 400 and 450 MHz frequency bands are assigned in some countries because they were previously used for first-generation systems. Most 3G networks in Europe operate in the 2100 MHz frequency band.
