Finland has shut down its final analog landline phone network, marking the end of nearly 150 years of copper-wire service.

The retirement began when telecom operator Elisa ended its fixed-line network for private customers and businesses after deciding earlier in the year to retire the system. Elisa’s decision followed other operators’ earlier pullbacks: Telia ended its own landline service in 2019 and DNA stopped supporting landline networks at the start of the year.

According to Finnish media, the number of landline phones in homes peaked in the early 1990s, but use steadily declined as mobile phones became more common. Finland’s mobile boom—anchored by firms including Nokia—accelerated the shift away from landline technology.

For years, landline-only plans dwindled to only a few thousand customers, with no new subscriptions sold for some time. After June 30, remaining access to landline-style services is expected to be limited to small local operators and primarily for local calling.

The shutdown follows a broader global transition from legacy copper infrastructure to digital networks, as voice and broadband services increasingly run over modern telecommunications systems.
