トルコの通信エリア

トルコ 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57 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、16 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。

トルコ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Turkcell、Vodafone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。

トルコの5G

• BTK auctioned 400 MHz of spectrum in the 700 MHz and 3.5 GHz bands on 16 October 2025, split into 11 packages. All 11 sold for 2.945 billion US dollars, or 3.534 billion including VAT.
• Turkcell took five packages for 1.224 billion dollars, Turk Telekom four for 1.094 billion and Vodafone two for 627 million.
• BTK set 1 April 2026 as the start of 5G service nationwide, with no change to existing tariffs. The licences run until 31 December 2042, and from 2029 to 2042 operators must put 5 percent of revenue into infrastructure each year.
• The licence terms raise the required share of domestically made network equipment from 45 percent in the 4.5G era to 60 percent, and require products whose rights belong wholly to Turkish firms, at 15 percent in the first stage and at least 30 percent overall, subject to availability.
• 5G was set to open in all 81 provincial centres first, with nationwide coverage targeted within two years. Just before launch, about 32 million of Turkey's roughly 95 million mobile phones were 5G compatible.
