サウジアラビアの通信エリア

サウジアラビア 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83 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、24 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。

サウジアラビ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STC、Mobily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。

サウジアラビアの携帯キャリア

サウジアラビアの旧世代ネットワーク

• stc announced the shutdown of its 3G services during 2023, starting in a few cities with completion planned for the third quarter. It kept 2G running so that phones limited to 2G or 3G could still make calls and send texts on its network.
• stc's published network plan for business customers set the fourth quarter of 2025 as the date to switch off its 2G network, as part of upgrading its 2G and 3G networks to 4G and 5G.

サウジアラビアの5G

• Saudi Arabia launched 5G New Radio in 2019. The regulator lists it as the successor to 4G LTE, 3G UMTS and 2G GSM, the mobile technologies that came before it.
• The regulator has assigned mobile spectrum by auction since 2017. Its fourth auction offered 400 MHz in the 3500 MHz band, and the fifth offered 600, 700 and 3800 MHz spectrum.
• In the November 2024 auction, stc won 40 MHz at 600 MHz and 100 MHz at 3800 MHz, Mobily won 20 MHz at 700 MHz and 100 MHz at 3800 MHz, and Zain won 30 MHz at 600 MHz.
• That auction raised the total spectrum licensed for mobile networks from 1110 MHz to 1400 MHz, and made Saudi Arabia the first country in Europe, Africa and the Middle East to license the 600 MHz band for mobile use.
• The regulator set out the 600, 700 and 3800 MHz auction to improve 5G coverage in remote areas, raise service quality on roads, at border crossings and along railways, and lift internet speeds.
• For the 2025 Hajj season, 5G coverage in Makkah, Madinah and the Holy Sites reached 99 percent and 4G coverage exceeded 99 percent, backed by more than 10,500 Wi-Fi access points.
• Saudi Arabia held a spectrum auction on 23 August 2022 in the 2100 MHz band for 5G non-terrestrial networks, such as satellites and high-altitude platforms, promising to connect rural areas and bring fast internet onboard aircraft.

サウジアラビアのネットワークについて

• The regulator counts about 21,000 villages and localities in the Kingdom whose coverage comes through national roaming between the operators.
• Local roaming lets a phone move onto another Saudi operator when its own has no coverage. It switches on automatically for voice and internet, costs nothing extra, and triggers a free text in Arabic and English.
• Mobile subscriptions in the Kingdom reached 68.2 million in 2024, growing 7 percent in a year.
• For the 2024 Hajj, operators allocated more than 6,200 towers across Makkah, Madinah and the Holy Sites, over 4,000 of them with 5G, a rise of 37 percent in 5G towers on the year before.
• The regulator runs a free coverage map service: enter a national address or pick a point on the map to see which operators' networks cover that location.
• In September 2025 two major submarine cables, SMW4 and IMEWE, were damaged in the Red Sea near Jeddah, disrupting connectivity across India, Pakistan, the Gulf and parts of Africa while traffic was rerouted.
• Zain is the Saudi landing party for the PEACE submarine cable. It also holds a stake in Blue Raman, a cable consortium of Google, Omantel and Sparkle, and is that system's landing party in the Kingdom.
