Some networks in regions such as for example the UNITED STATES, the, Canada Caribbean and South Usa make use of the 1900MHz frequency. To make use of these networks you may need what exactly is called a tri-band handset. This apparatus has the capacity to obtain not just the 900MHz and 1800MHz frequencies, but in addition the 1900MHz frequency. Assess your handset user guide to get out if your handset is tri-band and may function on the 1900MHz frequency.
