The last 2G tower
On August 3, 2026, T-Mobile powered down the last 2G transmitters in the United States. Somewhere in a drawer — dusty, long-forgotten — an original iPhone, 2007 vintage, went permanently silent. It had outlasted the network it was born into by nineteen years; the network had been running for thirty-five.
The Groupe Spécial Mobile committee convened in 1982 at the European Conference of Postal and Telecommunications Administrations, tasked with solving an embarrassingly simple problem: Europe had nine incompatible national cellular systems, and a phone purchased in Germany was useless in France. German executives on business in Paris could not call their offices from a pocket device. By February 1987, the committee had produced the first agreed GSM Technical Specification — nearly 3,000 pages of engineering consensus from delegations in Germany, Britain, France, and Italy. The initials survived when the name changed; “Groupe Spécial Mobile” became “Global System for Mobile Communications” on the standard’s transfer to ETSI in 1989.
The first commercial GSM call ran on July 1, 1991, in Helsinki. Finnish prime minister Harri Holkeri lifted a Nokia handset on Radiolinja’s newly lit network and rang Kaarina Suonio, the acting chief executive of Tampere. The network covered only three Finnish cities at launch. By 1995 it had ten million subscribers worldwide. By 2004, a billion. By 2005, more than 75 percent of every mobile subscription on the planet ran on GSM — a standard eventually operating across 219 countries.
What GSM got structurally right was the SIM: a removable chip carrying your identity, independent of any particular handset. Swap devices without swapping numbers; travel without swapping networks. Roaming, harmonised across borders, let a traveller use one phone across a dozen countries — the first time that had been possible. SMS launched commercially on GSM networks in 1995 and, within a decade, outpaced voice as the primary use of the network it rode on.
The original iPhone, released June 29, 2007, was a GSM device — not merely compatible, but exclusively dependent on it. It ran on AT&T’s EDGE network, a 2G variant, and could not touch Verizon’s rival CDMA towers at all. Steve Jobs never mentioned this on stage because there was nothing to mention: in 2007, 2G was simply the air every phone breathed. The device that reinvented the smartphone was running the same protocol as the Nokia 2110.
AT&T pulled its 2G network in 2017. Verizon went dark in 2020. T-Mobile, last of the Big Three, kept 2G alive because legacy payment terminals, alarm panels, and international roaming partners still depended on it. On August 3, 2026, it ran out of reasons to wait.
The frequencies are already carrying 5G. The SIM card that GSM introduced is still in every phone on Earth. A standard can go dark while the ideas it proved — portable identity, global interoperability, one network across every border — go on, becoming the next thing’s foundation.
