Quad Band Cell Phones, Discount Quad Band Phones, Free Quad Band Phones, Compare Quad Band Phones and Quad-Band Phones Sale Quad band literally means four (4) bands. It is a term used to describe a GSM mobile phone. The GSM standard originated in Europe, where mobile phones occupy two frequency bands: one in the 900-MHz range and one in the 1800-MHz range. When GSM technology crossed the Atlantic to the Americas, it was impossible to reuse the same European frequency bands since those had already been allocated to other devices by the FCC. Thus, a different pair of frequency bands were made available for GSM use: the 850 and 1900-MHz bands.
