Mobile Phones are not only tools of telecommunication, but also designed with various cool functions, such as TV, Bluetooth, Touch-screen, Digital Camera, Video Playback, A2DP, FM Radio, Multi-Sim Capacity, Games, COMPASS, MS Office, Web Surfing, etc.
To be an International Mobile Phone Store, we have to pay more attention to the NETWORKING FREQUENCY. All Mobile Phone networks worldwide use a portion of the radio frequency spectrum designated as Ultra High Frequency, or “UHF”, for the transmission and reception of their signals. The UHF band is also shared with TV, Wi-Fi and Bluetooth transmission. The cellular frequencies are the sets of frequency ranges within the UHF band that have been allocated for cellular phone use. We provide to worldwide consumers GSM phones that support three bands (900/1800/1900 MHz or 850/1800/1900 MHz) or four bands (850/900/1800/1900 MHz), and such phones are usually named as Tri-band Phone and Quad-band Phones (world phones). On the international trip, a multi-band phone is really conveniently.
Have a right Cell phone to match your style, your can also choose among the various style,including Bar Phone, Flip Phone, Slide Phone, etc.
Bar Phone – it is in the shape of a cuboid. It is named according to a candy bar in bobth the
size and the shape. This form factor is widely used by a variety of Mobile Phone manufacturers.
Normally Bar Phones have the screen and keypad all on one face. Many touch-screen phones(HiPhone) do away with keypads, but they are also bar phones.
Flip Phone – consists of two or more sections that are connected by hinges, which enable the user to flip or fold the phone device. Flipping open the Phone, the speaker and mic are closer to the user’s ear and mouth, so that the usability should be better. While flipping shut, the phone gets to be smaller so that it can be portable.
Slide Phone – composed of usually two segments that slide past each other on rails. In today’s Mobile Phone Market, most Slide Phones have a display segment which houses the speaker used for calls and the phone’s screen, while the other segment contains the keypad. It is good for the operator to take full physical keyboards or keypads portably just by retracting the phone when they are not in use.
