For the network to know which users are connected to the network, each phone uses a subscriber identification module (SIM) card. During these intervals, phones can transmit information.
GSM networks use Time Division Multiple Access (TDMA), which assigns time slots to multiple conversation streams, alternating them in sequence and switching between each conversation in very short intervals. GSM is the standard system for 80% to 90% of the world, which uses GSM technology for wireless calls, with notable exceptions of the United States and Russia. What is GSM? Julian Chokkattu/Digital Trends International travelers should take special note of the differences to avoid getting stuck with a phone that does not work somewhere they have to be - which is somewhere that 4G LTE or 5G does not exist. However, since these systems are still nominally in place, and around for the next year or so, it’s good to know what they are and the difference between them.
Both CDMA and GSM convert data from your smartphone into radio waves, and today they represent increasingly deprecated 2G and 3G systems based on competing technologies. That’s because these old standards are in the process of terminal decline.

Understanding the difference between Code Division Multiple Access (CDMA) and Global System for Mobiles (GSM) - two legacy radio telecommunications standards - is becoming less and less critical for consumers buying a new smartphone or switching carriers.
