When shopping for a new phone, you might find that there are several different varieties of phones and features. One feature to look at is the bands. Cell phone providers offer several different types of phones that work on different bands. The two most common types are Tri-Band and Quad-Band cell phones, and each works slightly differently from the other.
A band is simply a system used by the cell phone to communicate with the network, as well as place calls to others and send text messages. Each band works at a different frequency, and it used to be that mobile phones only supported access to one particular frequency, and therefore only one particular band. As time went on, however, more bands were incorporated into cell phones, and the phones that could only support one or two bands fell into obscurity, leaving essentially two types of phones: Tri-band and Quad Band.
A Tri-band phone is a phone that works with three different bands. The three bands may vary depending on the location where the phone is sold, but usually the phone's band capabilities are the two most popular bands of the phone user's home country, plus one additional band to allow for international roaming around the world. These phones are often the standard for most cell phone providers.
Quad Band Phones
Like the Tri-Band phones, the Quad Band phones also offer different uses of bands. But unlike the Tri-Band phones, Quad Bands offer the use of an additional band, making four total bands available to the cell phone's user. Quad Band phones are also known as "World band" phones, because the presence of the fourth band allows the phone to go essentially anywhere.
Pros and Cons of the Tri-Band phone
Because the phones can only handle three bands, these phones are generally cheaper than their Quad-Band counterparts. Furthermore, if you do not intend to do a great deal of international travelling in the next few years, then it's best that you buy a Tri-band phone. The biggest disadvantage in the Tri-band phones is that in the event that you do need to travel to another country, you will either have to purchase a Quad-Band phone or rent a phone with a calling plan in your destination.
Pros and Cons of Quad Band phones
With a Quad band phone, you will never have to worry about your phone being unusable in a foreign country, (But to avoid high roaming costs, be sure to get an international calling plan with your provider anyway.) In the event that you decide to take your phone to a different provider, having your phone be a Quad Band makes it much more likely to work with the new provider. The two main disadvantages lie in price and battery use: Quad bands generally are priced higher then Tri-bands, and because the phone has to listen to so many frequencies, battery life is typically much less then a Tri-Band phone.
