英領ヴァージン諸島の通信エリア

英領ヴァージン諸島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Flow、Digicel、CCT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。

英領ヴァージン諸島の携帯キャリア

• Flow: Cable & Wireless (BVI), which trades as Flow, holds 101.6 MHz of mobile spectrum: 2x12 MHz at 700 MHz, 2x8.8 MHz at 850 MHz, 2x15 MHz of AWS-1 and 2x15 MHz at 1900 MHz.
• CCT: Caribbean Cellular Telephone holds the most mobile spectrum of the three networks, 164 MHz in total, spread across the 850 MHz, 900 MHz, 1900 MHz and 2.5 GHz bands.
• Digicel: Digicel (BVI) holds 112 MHz of mobile spectrum, made up of 2x11 MHz at 700 MHz, 2x15 MHz at 1800 MHz, 2x15 MHz of AWS-1 and 2x15 MHz at 1900 MHz.
• Unitary licences: Flow, CCT, Digicel and BVI Cable TV first received unitary licences in 2007, when the market was liberalised. All four were renewed in December 2022 for another 15 years, with regulator reviews every five years.

• Some mobile operators told the regulator in 2025 that they want to keep offering voice and messaging over 3G and 4G for the foreseeable future, so 3G and 4G spectrum could not yet be refarmed for 5G.

英領ヴァージン諸島の5G

• CCT switched on the first 5G network in the Virgin Islands on 1 October 2025, with limited availability across much of the territory at launch, after upgrading its whole 4G LTE network to support the move.
• In March 2026 the regulator proposed a 5G spectrum award open only to the four unitary licence holders, offering each 2x10 MHz of low band and 70 to 100 MHz of mid band spectrum in the 600 MHz, 700 MHz, 2.3 GHz, 2.5 GHz and 3.3 to 3.7 GHz ranges.
• Holders of the proposed 5G authorisations would have to cover at least 98 percent of the population of each of Tortola, Anegada, Jost Van Dyke and Virgin Gorda and 95 percent of geographic locations, within five years on the standard rollout.
• The Virgin Islands has no frequency coordination agreement with the United States covering the neighbouring US Virgin Islands, and low band 5G signals can cause interference across 100 to 150 km of open water.

英領ヴァージン諸島のネットワークについて

• Operators reported that Hurricane Irma in 2017 affected almost 90 percent of the mobile network in the Virgin Islands, and that fewer than a third of the affected sites had been restored more than a month later.
• Most mobile sites in the Virgin Islands are not built to withstand a Category 5 hurricane, which the regulator describes as a weakness of the networks today that will remain under any 5G rollout.
• After severe weather, the mobile operators must report outages to the regulator within two to three hours of the all clear, listing the areas and number of customers affected, and update restoration times every 12 hours.
• Four international submarine cable systems land in the British Virgin Islands: ECFS since 1995, CBUS to Bermuda since 2009, the East West cable to the Dominican Republic and Jamaica since 2011, and PCCS since 2015.
• Mobile connections in the Virgin Islands well exceed the population, partly because many people keep a second or third prepaid SIM to use promotions and cheap calls within the same network.
• As of April 2025 the regulator had not licensed any low earth orbit satellite provider to serve the Virgin Islands and was still building a licensing framework for them.
