First: the US Virgin Islands are not the British Virgin Islands
This guide is about the US Virgin Islands (ISO code VI): St Thomas, St John and St Croix, capital Charlotte Amalie, an unincorporated territory of the United States that uses the US dollar and dials 911. It is a different place from the British Virgin Islands (VG): Tortola, Virgin Gorda, Jost Van Dyke and Anegada, capital Road Town, a British Overseas Territory. The two are roughly two kilometres apart at the closest point and they share a name, which is how people end up landing on St Thomas holding a plan that only works on Tortola.
US Virgin Islands (this page)
- • St Thomas, St John, St Croix, Water Island
- • Charlotte Amalie • US dollar • 911
- • US territory, US immigration rules
- • Our plans run on T-Mobile
- • 12 country plans, 1 GB to 20 GB plus unlimited
British Virgin Islands (different guide)
- • Tortola, Virgin Gorda, Jost Van Dyke, Anegada
- • Road Town • US dollar is used • British Overseas Territory
- • Not US territory, different entry rules
- • Our plans there run on FLOW
- • A USVI plan does not work there, and vice versa
If you are island-hopping across both, you need two plans. There is no product in our catalogue that covers the US and British Virgin Islands together.
A United States eSIM does not cover the US Virgin Islands
This is the counterintuitive part, and it costs people their first day. The USVI is American soil, it uses the dollar, everyone speaks English and 911 works. None of that changes what a travel eSIM is: a plan sold against a coverage list. We checked our own catalogue on 15 September 2026 and all 14 active "United States" data plans declare United States alone. Not one of them lists the US Virgin Islands. If you buy a USA plan and fly to St Thomas, you land with a profile that has nothing to connect to.
What does work, and what does not
Works in the USVI
- • A plan whose name says Virgin Islands US — 12 of them in our catalogue
- • Your own US postpaid line from AT&T, T-Mobile or Verizon, which treat the territory as domestic
Does not work in the USVI
- • A travel eSIM sold as a United States plan
- • A British Virgin Islands plan
- • The Caribbean Island Hopper regional plan — it covers Puerto Rico, not the USVI
- • Any global plan in our catalogue
The Puerto Rico trap
Puerto Rico and the US Virgin Islands are almost always named together, so it is reasonable to assume a Caribbean regional plan that covers one covers the other. It does not. The Island Hopper regional package in our catalogue lists 26 places and Puerto Rico is one of them; the US Virgin Islands are not on the list, and neither are the British Virgin Islands. Verified against our coverage data on 15 September 2026.

The network you actually get
Every one of our 12 US Virgin Islands packages declares exactly one network: T-Mobile, MCC-MNC 310-260. There is no second network to fall back on. If your phone ever offers you a manual network list on St Thomas, St John or St Croix, T-Mobile is the entry to pick. Choosing Liberty or Viya gives you a full signal bar and no data, because your plan has no agreement with them — a failure mode that looks like a broken eSIM and is not one.
What to expect island by island
We are not going to grade individual beaches, because nobody has published reliable per-beach signal data and inventing it would not help you. What is fair to say is the general shape of a small, mountainous, rebuilt island network:
Expect solid service
- Charlotte Amalie, the cruise berths and the shopping district
- Cruz Bay on St John and Christiansted and Frederiksted on St Croix
- The main roads and the airports on St Thomas and St Croix
- Harbours and marinas, where boats need to be reachable
Expect gaps
- Inside the Virgin Islands National Park on St John, which is most of the island
- Valleys and the lee side of ridges, on all three islands
- Open water between the islands and out on day sails
- The east end of St John, where the nearest tower may be a British one
The Coral Bay roaming trap
Tortola is close enough to St John that handsets on the east end and around Coral Bay regularly register on a British Virgin Islands network instead of a US one. Travellers on the vinow.com Virgin Islands forum and the TripAdvisor St John forum report being billed international roaming for it. If you are using your home US line, turn international roaming off before you drive east. If you are on one of our USVI eSIMs there is no bill to fear — your plan has no BVI agreement, so a British tower just means no data — but setting network selection to manual and picking T-Mobile keeps your phone from wandering.
Who runs the networks in the US Virgin Islands
The territory is small enough that the operator list has changed meaningfully in recent years, and a lot of travel pages have not caught up. The most common stale claim is that AT&T runs its own network here: it sold its Puerto Rico and US Virgin Islands operations to Liberty Latin America, and that deal closed on 2 November 2020.
T-Mobile
What our plans use
- • MCC-MNC 310-260
- • The single network declared by all 12 USVI plans
- • The one to choose in a manual network list
Liberty Mobile
Formerly AT&T
- • Took over AT&T's USVI and Puerto Rico network in November 2020
- • Widely used locally
- • Our plans have no agreement with it
Viya
The local incumbent
- • The territory's long-standing landline, cable and mobile operator
- • Smaller mobile footprint than the other two
- • Our plans have no agreement with it
Why the list matters: in a three-operator territory where your plan only has one of them, "full bars, no internet" is almost always a network-selection problem rather than a faulty eSIM. See the troubleshooting section below.
eSIM installation
iPhone
- Settings → Cellular / Mobile Data
- Tap Add eSIM or Add Cellular Plan
- Scan the QR code from your email
- Label the line, for example "USVI"
- Set it as the line for cellular data
- Turn Data Roaming ON for that line
Android
- Settings → Network & Internet
- Tap SIMs or Mobile Network
- Select Add eSIM or the + button
- Scan the QR code or enter the details manually
- Activate the profile
- Set it as the default for mobile data and turn roaming on
Install before you fly. Adding an eSIM profile needs an internet connection, which is exactly what you do not have when you step off the plane. Scan the QR at home on trusted WiFi, then simply switch the line on when you land.
How much data different trips actually use
These are ranges, not promises, and they are tied to what we actually sell for the territory: 1, 2, 3, 5, 10 and 20 GB bundles plus unlimited plans from 3 to 30 days.
Cruise passenger, one port day
Ashore at Charlotte Amalie or Frederiksted for six to nine hours, then back aboard
Data needs
1-3 GB
Why
A single port day is a small amount of data: maps, a taxi or tour confirmation, messages home and some photos. Our smallest plan is 1 GB over 7 days.
Worth knowing:
- ✓Install the eSIM before you sail, not in the terminal
- ✓Screenshot your all-aboard time so you never need data to check it
- ✓Expect congestion near the berths when several ships are in
- ✓Ship WiFi packages and a local eSIM solve different problems - the eSIM only works ashore
- ✓A shore excursion to the British Virgin Islands leaves US coverage entirely
Island hopping by ferry
Basing on St Thomas and crossing to St John, or working across to St Croix
Data needs
5-10 GB for a week
Why
Ferry times, taxi coordination and maps add up more than you expect, and the St John side has real coverage gaps to plan around.
Worth knowing:
- ✓Download offline maps for St John before you leave Cruz Bay
- ✓You lose signal on the crossings - that is every network, not your plan
- ✓On the east end and around Coral Bay your phone may find a Tortola tower first
- ✓St Croix is a flight or a long ferry, not a short hop
- ✓Set network selection to manual and pick T-Mobile if data drops with full bars
Beach and snorkelling week
Trunk Bay, Magens Bay, the reefs off St Croix, and not much of a schedule
Data needs
5-10 GB
Why
Beach days use less data than city days because the phone stays in the bag. The spikes come from uploading photos and video in the evening.
Worth knowing:
- ✓Upload from the accommodation, not from the sand
- ✓Check conditions before you drive out - cell service is better in town
- ✓Mineral sunscreen only: chemical sunscreen is banned in the territory
- ✓Buck Island and the park beaches are the thinnest coverage of the trip
- ✓A waterproof case is worth more here than extra gigabytes
Sailing and charters
A bareboat or crewed charter working the anchorages, often crossing into BVI waters
Data needs
10-20 GB, or unlimited
Why
You will be in and out of coverage all week. Weather, charts and shore bookings are the load, and the crossings are dead zones.
Worth knowing:
- ✓VHF channel 16, not your phone, is the emergency tool offshore
- ✓Download charts and forecasts in the harbour, before you slip lines
- ✓A charter that crosses to the BVI needs a second plan and your passport
- ✓Anchorages generally have service; the water between them does not
- ✓Unlimited plans exist for 3, 5, 7, 10, 15 and 30 days if you would rather not count
Remote work from a villa
Working US hours from St Thomas or St Croix with the laptop tethered
Data needs
20 GB or unlimited
Why
Video calls and file sync are the whole budget. Treat the eSIM as the backup that makes villa WiFi survivable rather than the other way round.
Worth knowing:
- ✓Test tethering before your first meeting, not during it
- ✓The territory is UTC-4 year round - one hour ahead of US Eastern in winter, level with it in summer
- ✓Hurricane season runs 1 June to 30 November; have an offline plan
- ✓Sign up for Alert VI notifications at vitema.vi.gov
- ✓A 30-day unlimited plan is usually the right shape for a month-long stay
Photo and video heavy trip
Uploading daily, or working - drone footage, reels, client delivery
Data needs
20 GB or unlimited
Why
Upload volume, not browsing, decides this. Our largest fixed bundle is 20 GB over 30 days; beyond that the unlimited plans are the honest answer.
Worth knowing:
- ✓Batch uploads where coverage is good rather than trickling them all day
- ✓Cruz Bay and Charlotte Amalie are far better upload points than the park
- ✓Raw video will outrun any fixed bundle in a few days
- ✓Check the national park rules before flying anything
- ✓Keep a local copy - you will not always have the bandwidth to re-send
One thing that applies to every trip on this list
Whatever size you pick, the plan has to say Virgin Islands US. A United States plan does not cover the territory, a British Virgin Islands plan does not cover it, and neither does the Caribbean regional package — that one includes Puerto Rico but not the USVI. If your itinerary also takes in Tortola or Virgin Gorda, that is a second plan and a separate guide.
Around the islands, and where connectivity matters
St Thomas
The busiest of the three and one of the busiest cruise ports in the Caribbean. Charlotte Amalie is the capital, the shopping district and the reason most first-time visitors come.
- • Magens Bay, the best-known beach, charges an entrance fee
- • The Skyride to Paradise Point runs up from the harbour
- • Red Hook is the ferry terminal for St John
- • Cyril E. King Airport (STT) is the main gateway
St John
Most of the island is Virgin Islands National Park. Cruz Bay is the arrival point and the one place with real infrastructure; beyond it, plan for patchy service.
- • Trunk Bay has a marked underwater snorkelling trail
- • Coral Bay and the east end are where the BVI roaming trap lives
- • Download trail maps before you set out, not at the trailhead
- • Reached by ferry from Red Hook or Charlotte Amalie
St Croix
The largest island, further south and separate from the St Thomas / St John pair. Reached by seaplane, small aircraft or a long ferry rather than the short hop.
- • Christiansted and Frederiksted are the two towns
- • Buck Island Reef is a national monument, reached by boat
- • Point Udall is the easternmost point of US territory
- • Henry E. Rohlsen Airport (STX) serves the island
On the water
Harbours and anchorages are generally within reach of a tower. Open water is not, on any network.
- • Save charter confirmations offline before boarding
- • VHF channel 16 is the distress and calling channel, not your phone
- • Check the forecast before you leave the dock, not after
- • A day sail to the BVI is a border crossing — bring your passport
Troubleshooting
Full signal bars but no internet
The most common failure in a territory with three operators and a plan that only has one of them. Your phone has registered on Liberty or Viya, which your plan cannot use.
- • Settings → Mobile Network → Network selection → switch off Automatic
- • Choose T-Mobile from the list
- • Check Data Roaming is ON for the eSIM line
- • Check the eSIM line is set as the one used for cellular data
You bought a plan and it will not connect at all
Check the plan name before anything else. A United States plan and a British Virgin Islands plan both look plausible and neither covers the USVI. The plan has to say Virgin Islands US.
Your home carrier billed you international roaming
On St John you were probably on a Tortola tower. The USVI itself is domestic for AT&T, T-Mobile and Verizon; the British Virgin Islands are not. Turn international roaming off on your home line, or lock the network to a US one, particularly on the east end and around Coral Bay.
No service between islands
Normal. There is no coverage over open water on any network. Service returns as you approach shore. Download maps and tickets before the crossing.
Slow when a cruise ship is in
St Thomas can take several thousand extra people in a morning, all of them reaching for their phones at the same berths. Congestion near the cruise docks and in Cruz Bay at ferry times is real; it eases a few streets away and outside peak arrival windows.
Emergency contacts
Emergency number
911
911 covers police, fire and medical throughout the US Virgin Islands, exactly as on the mainland. The 911 system is administered by VITEMA, the territorial emergency management agency.

Sector San Juan is the Coast Guard command responsible for Puerto Rico and the US Virgin Islands.
A note on what is not on this list. Earlier versions of this page carried ferry, taxi, airport and tourism-office numbers we could not confirm against an official source, so they have been removed rather than left to rot. Every number above was checked on 15 September 2026.
2017, and why old guides describe a network that no longer exists
Hurricanes Irma and Maria both struck the US Virgin Islands within two weeks of each other in September 2017. Between them they destroyed a very large share of the territory's pole-mounted power and telecoms plant, and the restoration effort ran for years afterwards: the FCC created the Connect USVI Fund, which together with its Puerto Rico counterpart directed close to a billion dollars towards restoring and expanding communications in the two territories, and the US Government Accountability Office has published several reports tracking that work.
That cuts both ways for a travel guide. Pages written in 2018 describe an emergency; pages written without checking describe a mainland-grade network. Neither is right today. What is accurate is that the commercial networks on the three main islands were substantially rebuilt, and that this is still a small, mountainous territory where coverage follows the roads and the towns and thins out in the national park and on the water.
Hurricane dates and the federal restoration programmes are from FCC and GAO publications. We are not publishing a coverage percentage for the territory, because we have not found one we can stand behind.
Entry rules, local law and etiquette
Entry
The US Virgin Islands are US territory for immigration purposes, so the mainland rules apply. Visa Waiver Program nationals need an approved ESTA before boarding; everyone else needs the appropriate US visa. US citizens travelling from the mainland do not need a passport, but do need photo ID — and they do need a passport for a day trip across to the British Virgin Islands, which is a different country. Check your own case at esta.cbp.dhs.gov and travel.state.gov rather than relying on any travel page.
Worth knowing
- Greet before you ask. "Good morning" or "good afternoon" first, then your question.
- Driving is on the left — the only US jurisdiction where it is — in left-hand-drive cars.
- Bring mineral sunscreen. See the note below: this one is law, not advice.
- Tipping follows US practice.
- All beaches are public, but the land you cross to reach them may not be.
Worth avoiding
- Touching or standing on coral.
- Rushing an interaction. The pace is the pace.
- Assuming the territory is interchangeable with the mainland — or with the BVI.
- Leaving valuables visible in a parked rental car.
- Chemical sunscreen. It is banned, and it is enforced at the point of sale.
The sunscreen law
The US Virgin Islands banned sunscreens containing oxybenzone, octinoxate and octocrylene — known locally as the "Toxic 3 Os" — making it the first US jurisdiction to do so. The law was signed in July 2019; importation stopped that September and the ban on sale, distribution, possession and use took effect on 30 March 2020. In practice that means mineral sunscreen with zinc oxide or titanium dioxide. Buy it before you travel; it is easier than finding it on arrival.
