How to Obtain A Global Mobile Phone For Everyday Use
Cellphone service providers in different regions of the world use slightly different signal frequencies. Phones that employ Global System for Mobile Communications, or "GSM," the world's most prominent cellphone technology, use "quad-band" frequencies. On the other hand, some U.S. cellphones use dual- or tri-band frequencies and employ Code Division Multiples Access, or "CDMA," a competing technology. Obtain a quad-band global mobile phone for everyday use in the U.S. to ensure you can also use it whenever you travel abroad.
