Tri-Band Mobile and Smart Phones
Tri-Band mobile and smartphones are ideal for those who use their phone across the world as the phones work in three different radio frequency bands. A tri-band phone has the functionality to be used abroad and can be used for roaming as it has the capability to switch transmission to the appropriate frequency used in the specific country you are travelling in.
Benefits of Tri-Band Mobile Phones and Smartphones
Phones usually come in three different bands; dual-band, tri-band and quad-band . Dual bands will only work in some regions of the world, tri-bands give a much greater coverage without the expense of quad-band phones. If you travel frequently, you want to make sure that your mobile phone works, wherever you are in the world without worrying about requiring different communication devices. A tri-band phone will ensure you have an excellent phone coverage in most regions of the world.
For more remote areas, a quad-band may be needed, however, quadband phones are generally more uncommon and therefore more expensive. Tri-band phones are much more ordinary, and many of the popular phone models offer tri-band as a feature.
What to look for
When purchasing a tri-band phone, it is best to check your common locations and the frequencies those geographic areas use. Different types of tri-band phones will support different frequency types, so it is best to check that the phone will enable you to use it in the areas you commonly reside in or visit.
Types of Tri-Band Phones
