サン・マルタンの通信エリア

サン・マルタン 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22.3 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、3.6 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。

サン・マルタン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Orange Caraïbe、Digicel、Dauphin Telecom、Free Caraïbe、UTS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。

サン・マルタンの携帯キャリア

• Five networks: The regulator's shutdown table for Saint-Martin lists five mobile operators: Dauphin Telecom, Digicel, Free Caraïbe, Orange and UTS. Dauphin Telecom and Free Caraïbe never ran a 2G network there.
• Free Caraïbe: Free Caraïbe began selling mobile plans in the French Caribbean on 17 May 2022. At launch it had 10 mobile sites on Saint-Martin covering 97 percent of the population with 4G, with 2 more sites planned to reach 98 percent.

サン・マルタンの旧世代ネットワーク

• Digicel switched off 2G on Saint-Martin on 1 July 2025, and UTS has also ended its 2G service. Orange began with Peatree Hill, Rambaud and Marigot on 19 May 2026 and scheduled the switch off everywhere on the territory for 26 September 2026.
• Orange plans to close its 3G network in 2028, and the other operators have not announced a 3G date. The regulator warns that a phone which cannot carry calls over 4G, known as VoLTE, will stop making calls once the older networks close.

サン・マルタンの5G

• Spectrum for 5G was awarded on 25 July 2023. Dauphin Telecom, Free Caraïbe and Orange Caraïbe received frequencies in both the 700 MHz and 3.4 to 3.8 GHz bands, and Digicel received 3.4 to 3.8 GHz only.
• Each winner took a 50 MHz block in the 3.4 to 3.8 GHz band in return for coverage commitments, and the remaining 180 MHz went to auction on 1 June 2023. The whole 700 MHz band, 20 MHz duplex, was auctioned on 18 April 2023.
• Free Caraïbe's licence runs from 25 July 2023 to 24 July 2038 and can be extended to 2043. It paid 2,000 euros for 5 MHz duplex at 700 MHz on Saint-Martin, and nothing for three extra 10 MHz blocks that put it at 3620 to 3700 MHz.
• Within five years of the award, half of Free Caraïbe's larger sites, and at least 2 on Saint-Martin, must use the 3.4 to 3.8 GHz band to offer at least 100 Mbit/s per 10 MHz block with latency of 5 milliseconds or less.

サン・マルタンのネットワークについて

• Free Caraïbe's licence names five areas of Saint-Martin that must get voice, text and fast mobile internet within 36 months of July 2023: Concordia, Colombier, Oyster Pond, Cul de Sac and Quartier d'Orléans. Operators must share new masts built for these areas.
• Hurricane Irma on 6 September 2017 destroyed 90 to 95 percent of buildings and infrastructure on Saint-Martin and Saint-Barthélemy, took down GSM antennas and broke a submarine telecom cable. When the mobile network returned it was saturated, and restoring service took several weeks.
• After Irma the fixed networks, previously strung overhead, were rebuilt underground through Tintamarre, a company set up from November 2017 to build and run buried ducts for the three fibre operators on the territory: Orange, Dauphin Telecom and THD Tel.
