GSM stands for Global System for Mobile Communications: Often referred to as 3G mobile or 3g wireless, there is no other system anywhere in the US cellular world that covers as many unlocked cell phones and prepaid or pay as you go mobiles. Indeed, the GSM standard governs the activities of the largest locked cell phone providers in the USA, namely T-mobile and AT&T - thereby incorporating the most pdas and latest cell phone models of all the major manufacturers (for example: Nokia n95, Apple iphone, Blackberry Bold). For every 1000 numbers in the cellular phone directory at any one time, 800 (approximately) are GSM connected. The other noted standard is known as CDMA favored by Sprint and Verizon as the noted providers in the USA.

GMS is in fact a travelers “dream” standard. The GMS system is most differentiated by being digital in nature, thus making data communications very easy to incorporate and creating greater range of capability. A primary reflection of this cutting edge capability was the recent emergence of the Short Message System (SMS) also known as “text messaging” - since emulated by other standards. The GSM standard has allowed the power of choice to shift from the traditional locked phone providers and operators of mobile services to the end-user, making unlocked cell-phone communications cheap. The GSM standard works effectively through SIM cards that can be moved from phone to phone and moreover adjusted or unlocked to fit in with any carrier. This is in contrast to the locked phone concept advocated by AT&T, T-Mobile, Verizon and Sprint until upended by class action law suits, which previously tied customers to one carrier and therefore subjected them to pricing abuse.
