GSM stands for Global System for Mobile Communications and was offered commercially in 1991. Aside from CDMA technology, this is one of the most common transmission technologies. GSM phones require a SIM card to be used and these cards store all of the usersí information such as contacts and productivity entries. AT&T is the most popular provider and thanks to third-party services, people are able to send text messages to each other. GSM is the standard in Europe and Asia which just proves its resilience in any situation.
Essentially a memory chip that can be transported from one phone to another, this is the secret to GSMís success. Any compatible phone can have a SIM card inserted into it and can be used just as if it were your own phone.
