What is GSM (Global System for Mobile communication)?
GSM (Global System for Mobile communication) is a digital mobile network that is widely used by mobile phone users in Europe and other parts of the world. GSM uses a variation of time division multiple access ( TDMA) and is the most widely used of the three digital wireless telephony technologies: TDMA, GSM and code-division multiple access ( CDMA ). GSM digitizes and compresses data, then sends it down a channel with two other streams of user data, each in its own time slot. It operates at either the 900 megahertz ( MHz) or 1,800 MHz frequency band.
What are GSM vs. CDMA vs. LTE differences?

An embedded SIM, or eSIM, cannot be removed. It’s a programmable SIM card that’s physically connected (soldered) to the motherboard. It does everything an external SIM card does, only you can’t physically remove it without breaking open the phone and unsoldering the chip.
What is a SIM card?
This is the more familiar solution of the two. It’s a Subscriber Identity Module that sits in a special tray and slides into a device like a drawer. It’s typically supplied by a carrier and programmed with your device’s unique serial number, IMEI, ICCID, authentication key, the device PIN, SMS messages, and so on. Without this card, your phone can’t make any standard calls outside dialing 911 across a wireless network.

Each generation is able to support more users and has better data transfer capabilities. The first generation was analog cellular phones . When carriers switched to 2G digital systems in the 1990s, they chose among several competing options; some of them died out, but CDMA and GSM are the two 2G camps that survived.
When did 2G phones come out?
The first generation was analog cellular phones. When carriers switched to 2G digital systems in the 1990s , they chose among several competing options; some of them died out, but CDMA and GSM are the two 2G camps that survived.
