Global System for Mobile Communications (GSM) is an ETSI standard for second-generation (2G) digital cellular networks used by mobile phones and tablets. In Finland in December 1991. [2] By mid-2010s, it had over 90% market share and operated in 193 countries and territories.

2G networks replaced analogue 1G networks. GSM originally described a digital, circuit-switched network for full duplex voice. This expanded to include data communications, first by circuit-switched transport, then by packet data transport via GPRS and EDR-GSM (EDGE).

The 3GPP developed 3G UMTS, 4G LTE Advanced, and 5G standards, which are not part of ETSI GSM.

The GSM Association owns “GSM.” Full Rate was the (initially) most popular voice codec.

Due to the network’s popularity in Europe, “GSM” was briefly used as a generic term for mobile phones in France, the Netherlands, and Belgium. Many Belgians still use it. In the late 2010s, carriers began shutting down GSM networks.

Former Finnish PM Harri Holkeri made the world’s first GSM call on 1 July 1991, calling Tampere’s deputy mayor using a Nokia-Siemens-operated network. [11] The following year, Vodafone UK and Telecom Finland signed the first international roaming agreement.


Work began in 1991 to expand GSM to 1800 MHz, and the first 1800 MHz network, DCS 1800, went live in the UK in 1993. Telstra was the first network operator outside Europe to deploy a GSM network, and the first hand-held GSM phone was released.

In 2000, the first GPRS-compatible phones went on sale. In 2001, the first UMTS (W-CDMA) network was launched. 500 million GSM users worldwide. In 2002, MMS and the 800 MHz GSM network went live. Enhanced Data rates for GSM Evolution (EDGE) services began in 2003, and GSM subscribers surpassed 1 billion in 2004.

By 2005, GSM networks served 1.5 billion subscribers, 75% of the global cellular market. First HSDPA-capable network launched in 2005. First HSUPA launched in 2007. HSPA is a 3G technology, not part of GSM. 2008 saw three billion GSM subscribers worldwide.
