Mobile frequencies (bands) vary between countries. Most modern handsets can pick up more than one frequency, so they can be used in more than one location around the world.
The names dual, tri, quad and penta refer to mobiles which can pick up more than one band. Multi-band mobiles are more flexible, and the better signal coverage they offer makes them a good choice of handset for those who regularly travel abroad.
What is a mobile band?
- Dual, tri, quad, and penta -bands describe the number of radio frequencies that a phone can use
The band or bands used dictates:
- whether your phone can access a signal abroad
- which countries it can get a signal in, and
- how good that signal will be
- There are fourteen different bands in total, and two main bands (900 and 1800 in the UK & Europe, 850 and 1900 in North America)
- Bands are grouped by region. For example; most European phones use the frequency range 900 and 1800, so a handset bought in Europe will detect radio signals within that particular band
- Check with your phone's manufacturer for more information about your handset's GSM band. They will be able to tell you more about signal coverage for your travel destination, and will also offer phone rental services in the event that your handset can't be used on your travels. Some mobile phone companies also offer a temporary band-switching service, so check to see if this service is available for your handset.
