2G, understood as GSM and CdmaOne, has been superseded by newer technologies such as 3G (UMTS / CDMA2000), 4G (LTE / WiMAX) and 5G . However, 2G networks were still available as of 2023 in most parts of the world, while notably excluding the majority of carriers in North America, East Asia, and Australasia. [5] [6] [7]
2G (or 2-G) provides three primary benefits over their predecessors: phone conversations are digitally encrypted; 2G systems are significantly more efficient on the spectrum allowing for far greater mobile phone penetration levels; and 2G introduced data services for mobile, starting with SMS (Short Message Service) plain text-based messages. 2G technologies enable the various mobile phone ...
In general, the types of phones and other devices supported by the MVNOs are in line with the technologies used by the Mobile Network Operator (MNO), the underlying cellular network provider. 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.
While a phone purchased from a given carrier can be expected to work with that carrier, making 4G voice calls on another carrier's network (including international roaming) may be impossible without a software update specific to the local carrier and the phone model in question, which may or may not be available (although fallback to 2G/3G for ...
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.
If you're looking for a way to invest in 4G LTE wireless networks with as little pain and risk as possible, MIPS Technologies (NAS: MIPS) just joined the shortlist of research candidates. Click ...

Models aside from the 4G versions communicate on second-generation cellular networks only, rather than later standards such as 4G, and will no longer work when 2G networks are phased out, as has been happening since 2016 in different regions. These include: Nokia 105 (2013), released in 2013 and aimed at markets in developing nations. [1]
