GSM 900/1800 are the cellphone frequencies used in most of the world. GSM 850/1900 are the cellphone frequencies used primarily in North America. Please make sure that your cellphone has either GSM 850 or GSM 1900 so it will work in the USA. If it is not compatible, we sell GSM 850/1900 cellphones in the “Phones” section of our website.
