A quad band mini cell phone is a mini cell phone that can operate on four frequency bands. It is marketed as being smaller and lighter than the average cell phone. These types of phones appeal to people who have mobile lifestyles and who want a highly portable device that can work in many locations. Choosing the best quad band mini cell phone will depend mostly on which features you want, because some features are available only in certain phones.
Quad band cell phones work on the 850 megahertz (MHz), 900 MHz, 1800 MHz and 1900 MHz frequencies. As a general rule, the 850 and 1900 MHz bands provide service in North and South America, and the 900 MHz and 1800 MHz frequency bands make a phone functional in Europe and Asia. Quad band phones differ from tri band and dual band phones in that they theoretically can provide service anywhere in the world where they can get reception. Tri band and dual band phones are restricted to providing service where those three or two frequency bands, respectively, are used.
When choosing a quad band mini phone, you should verify that the phone does, in fact, operate on all four frequency bands. Selecting a phone that operates on fewer than the four possible frequency bands can result in service interruptions. Its use also can be limited to specific regions.
It's also important to determine which phone features are the most important to you. You should determine which features you will use most so that you can ensure that those activities are compatible with the mini phone. A quad band mini phone's size is reduced, so the number of complex features it boasts might be limited. For instance, checking email several times a day can be difficult on a mini phone, because its screen likely is small.
A quad band mini phone can come with dual Subscriber Identity Module (SIM) card capability, Bluetooth® or a QWERTY keyboard, but not all mini cell phones will offer these features. It's not uncommon to come across a phone like this that has been stripped down to its essentials, offering only basic features such as calling and texting capabilities. Others can have advanced technological features such as touch screens.
