モンゴルの通信エリア

モンゴル 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35 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、8 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。

モンゴル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Mobicom、Unitel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。

モンゴルの携帯キャリア

• Market: In August 2024 Mongolia had 4.9 million mobile subscriptions for a population of 3.5 million. Mobicom held 36.9 percent of the market and Unitel 34 percent, and operators earned an average of 16,544 tugrik per user a month.
• Mobicom: Mobicom is a consolidated subsidiary of Japan's KDDI, which has invested since its founding in 1995 alongside Sumitomo Corporation and Newcom. In 2017 it launched Mongolia's first carrier aggregation service, in Ulaanbaatar and Erdenet.
• Unitel: Unitel launched Mongolia's first 4G LTE network in 2016, according to its chief executive, and says mobile internet use grew tenfold in the years after.
• Starlink: On 6 July 2023 the regulator approved two licences for SpaceX's Starlink, allowing low orbit satellite internet to be sold in Mongolia.

モンゴルの5G

• Five operators received 5G spectrum licences in May 2025: Unitel, Mobicom, Skytel, GMobile and ONDO. Each was allocated 100 MHz, and existing 4G systems are to move to 5G on that spectrum through 2027.
• The rollout is tiered: Ulaanbaatar first, then provincial centres, then soum centres, with the selection terms asking for remote settlements to be reached as early as possible. Operators plan the work for 2025 to 2029 and budget 1.4 trillion tugrik over five years.
• Unitel lit Mongolia's first 5G test station on Sükhbaatar Square in August 2022 and tested in all 21 provincial centres in October 2023. Commercial service opened on 16 May 2025 in Ulaanbaatar and the 21 provincial centres, with no settings needed on a 5G phone.
• The national target set at launch is 5G coverage for 70 percent of the population by 2027, two years after commercial service began.

モンゴルのネットワークについて

• Regulator statistics for 2024 counted 4.89 million mobile users, 4 million of them on 4G, and 55,540 kilometres of transmission lines, 78 percent of it fibre optic.
• Landlocked between Russia and China, Mongolia reaches the internet over land. Mobicom's backbone has cross-border links with Chinese carriers and with Russia's Megafon and TTK, and the ERMC terrestrial cable runs from Europe through Russia and Mongolia to China.
• Coverage is concentrated in towns. British phones generally work in the cities, but large parts of rural Mongolia have no network coverage at all, and outside the capital only about 10 percent of roads are paved.
