3G networks offer greater security than their 2G predecessors. By allowing the UE (User Equipment) to authenticate the network it is attaching to, the user can be sure the network is the intended one and not an impersonator. 3G networks use the KASUMI block cipher instead of the older A5/1 stream cipher. However, a number of serious weaknesses ...
In addition to simply providing faster speeds, they predict that 5G networks will also need to meet the needs of new use-cases such as the Internet of things (IoT) as well as broadcast-like services and lifeline communications in times of disaster. 3GPP has set an early revision, non-standalone release of 5G called New Radio (5G NR).

Cellular network standards and generation timeline. This is a comparison of standards of wireless networking technologies for devices such as mobile phones.A new generation of cellular standards has appeared approximately every tenth year since 1G systems were introduced in 1979 and the early to mid-1980s.
Originally 2G networks were voice centric or even voice only digital cellular systems (as opposed to the analog 1G networks). Typical 2G standards include GSM and IS-95 with extensions via GPRS, EDGE and 1xRTT, providing Internet access to users of originally voice centric 2G networks. Both EDGE and 1xRTT are 3G standards, as defined by the ITU ...
3G mobile telephony was relatively slow to be adopted globally. In some instances, 3G networks do not use the same radio frequencies as 2G so mobile operators must build entirely new networks and license entirely new frequencies, especially so to achieve high data transmission rates.
GSM and related 2G and 2.5G standards, including GPRS and EDGE; UMTS and related 3G standards, including HSPA and HSPA+; LTE and related 4G standards, including LTE Advanced and LTE Advanced Pro; 5G NR and related 5G standards, including 5G-Advanced; An evolved IP Multimedia Subsystem (IMS) developed in an access independent manner
2G, or second-generation cellular network technology, marks the transition from analog to digital communication in mobile networks. Defined by the European Telecommunications Standards Institute (ETSI) under the GSM standard, which became the first globally adopted framework for mobile communications, 2G was first commercially launched in 1991 by Radiolinja (now part of Elisa Oyj) in Finland.

All major and regional MNOs use 4G LTE / LTE Advanced and 5G NR protocols (2G and 3G having been deprecated and shut down), with GSM technologies. However, many MVNOs tend to sell somewhat older phone models (e.g. ones discontinued by the host networks), which can affect whether all technologies supported by the carrier network are usable by ...
