エストニアの通信エリア

エストニア の数値が意味すること

重要な数値は2つあり、どの会社も引用するのはそのうち1つだけです。一般的な速度は95 Mbps。調子のいいときがどれくらいかを示す数字です。

読む価値があるのは10パーセンタイル、30 Mbpsのほうです。駅の上の基地局が混み合い、周りの全員が同じ電波につながっている、その日の下位1割のときの速度です。中央値が高くて下限が低い国は、本当に必要になるその瞬間まではみごとに動く国だということです。

ビデオ通話やテザリングが欠かせない旅なら、一般的な速度ではなく混雑時の数値を基準に計画してください。

エストニアで回線が混んだときに起きること

混雑は故障ではなく、火曜の夜です。問題は、そのときeSIMに何ができるかで、たいていの旅行用eSIMの答えは「何もできない」です。国ごとに卸契約が1つ、ネットワークが1つ、路上に立ったまま他社のeSIMをもう1枚買う以外に逃げ道がありません。

ここではOrbisloの通信はTelia、Elisaを通ります。いま乗っているネットワークが劣化したら、旅行の途中でも、お客様が頼まなくても別の回線へ移します。そのときに邪魔をするのではなく、あとからお知らせします。

エストニアの携帯キャリア

• Telia Eesti: Telia opened Estonia's first public 5G on 11 November 2020, on a handful of streets in Tallinn, Tartu and Pärnu for a few thousand customers, using its existing frequencies before any 5G auction had taken place.
• Telia Eesti: Telia has said it will not start closing its 2G network before 2029. 2G still carries a small share of voice calls and serves card terminals, meters, alarms and cars, while more than 80 percent of Telia's mobile calls already run over 4G.
• Elisa Eesti: To prepare for its 3G switch-off, Elisa added more than 250 new 2G base stations across Estonia and moved most customers onto VoLTE, so older phones keep voice service on 2G while data needs a 4G or 5G device.
• Telia, Elisa, Tele2, STV: The regulator classes four communications companies as providers of vital services: Tele2, Elisa, STV and Telia. In 2025 it recorded nine significant incidents disrupting call or internet services, but no complete communications outage.

エストニアの旧世代ネットワーク

• Telia switched off 3G county by county through 2023, starting in Läänemaa in March and ending in Tartu County on 20 November and Tartu city on 21 November. Its 2G network stayed on for calls from phones without VoLTE.
• Elisa began closing 3G in Rapla County in May 2024 and finished on 25 November 2024 in Tallinn and Harju County. Customers kept 2G, 4G and 5G.
• Tele2 was the last Estonian operator to close 3G. After starting in Rakvere in February 2025, it switched off Rapla, Järva, Jõgeva, Viljandi, Lääne-Viru and Ida-Viru counties on 6 November and Tartu, Valga, Põlva, Võru, Narva and the Peipus shore on 20 November 2025.
• With 3G gone on all three networks, phones without VoLTE can still make calls over 2G, but old USB modems and routers that only support 3G have to be replaced. Tele2 advises checking that VoLTE is switched on in phone settings.

エストニアの5G

• Estonia auctioned three 3410 to 3800 MHz licences in 2022. Elisa won the first on 27 May for 7,206,208 euros, Telia the second on 15 July for 8,500,300 euros, and Tele2 the third unopposed for 1,597,000 euros.
• Each 3.5 GHz licence required a 5G service on at least 3GPP Release 15 within a year, and at least 200 active base stations within two years, no more than 100 of them in Harju County and at least five in every county.
• In the 700 MHz auction that began on 8 November 2022, Elisa, Tele2 and Telia each won two 2x5 MHz licences. Holders must reach 50 percent coverage in each county within two years and 95 percent within four.
• Ida-Viru, Jõgeva, Tartu, Põlva and Võru counties are exempt from the 95 percent 700 MHz target because Russian television broadcasting limits how the band can be used there, so low-band 5G in south-east and north-east Estonia can be thinner.
• Telia launched Estonia's first standalone 5G, branded 5G+, on 8 April 2026 with 5G voice calling (VoNR). At launch only a handful of devices could use it, including the Xiaomi 15T Pro and Nothing Phone 4a models.
• Since 2022 any operator running 5G non-standalone or newer, or providing a vital service, must get a permit from the regulator for the hardware and software in its network, a check that the equipment does not threaten national security.

エストニアのネットワークについて

• A 2025 consultation found 93 stretches along nine main highways and three railway lines, about 412 km in total, where 5G needs improving. The state has earmarked 18.72 million euros of EU regional funds to build masts along these corridors.
• In the last days of 2025, faults hit four subsea cables linking Estonia to Sweden and Finland and one to Hiiumaa island. A ship with its anchor chain in the water was detained by Finland, yet end users saw no noticeable impact and international links kept working.
• On 25 December 2024 three subsea cables between Estonia and Finland were damaged, two of them owned by Elisa and one by CITIC Telecom. All services and links between the two countries kept working, with no noticeable effect on users.
• Globalstar runs a satellite ground station at Kilingi-Nõmme in south-west Estonia, one of four in Europe relaying Apple's emergency SOS messages, and began expanding it in 2025.
• Close to 2 million SIM holders used mobile service in Estonia at the end of 2025, and about 96,000 customers, 13 percent of internet users, relied on 4G or 5G fixed wireless as their home connection.
• A spot check at the end of 2024 found operators meeting their 5G licence terms. For some operators the 700 MHz coverage maps matched field measurements more than 95 percent of the time, and 3.5 GHz base station counts matched licence conditions.
• Global Connect plans a new cable ring linking Finland, Estonia and Sweden, with 250 km of fibre across Estonian land and 1,250 km laid at sea. The 40 million euro project is due for completion in 2027.
