FairSIM eSIM for Montserrat
Montserrat is a small British territory in the Leeward Islands with two thirds of it closed off. The Soufrière Hills volcano buried Plymouth from 1995 onwards, and life moved to the green north around Brades, Sweeney's and Little Bay. You get there by a 20-minute flight from Antigua to John A. Osborne Airport at Gerald's, or on the ferry into Little Bay. Either way you arrive in a place where plans are made by phone call and WhatsApp, not by app.
That is exactly why you want data on landing. There is no ride-hailing service, so taxis and car rentals are arranged directly with the driver or the owner. Guesthouses and villas confirm by WhatsApp. Ferry and flight times shift with weather and demand, and the Montserrat Volcano Observatory publishes hazard-level updates that decide where a guide can take you that week. A phone with a working line saves a lot of standing around.
A FairSIM eSIM here roams onto Digicel or FLOW, the two networks on the island, on 4G LTE. Install it over Wi-Fi at home, switch it on when you land, and skip the shop hours entirely. One local rule to plan for: the southern Exclusion Zone is off limits without permission, and the accessible zones are entered with a licensed guide or by police clearance, so the buried city is something you view from Garibaldi Hill or Jack Boy Hill rather than wander into.

Montserrat eSIM plans
Plan starts: On first data use
Coverage in Montserrat
- 4G LTE5G
Digicel
Caribbean-wide operator with 4G LTE across Montserrat's populated north. A common host for travel eSIMs in the Leewards.
- 4G LTE5G
FLOW
The Cable & Wireless brand, and the main fixed-line and broadband provider on the island as well. 4G LTE on the mobile side.
4G LTE on both networks, with 3G and 2G as fallback. There is no 5G in Montserrat, so do not plan around it.
Typical speed: Good enough for maps, messaging, streaming and video calls in the north. Montserrat is too small for published median speed figures, so treat any number you see elsewhere with suspicion.
The inhabited north is well covered: Brades, Salem, Olveston, Woodlands, St Peter's, Little Bay, Carr's Bay and the airport at Gerald's. Signal drops inside the deep ghauts and on the Centre Hills trails, and coverage toward the Exclusion Zone boundary is patchy. Download offline maps before you hike.

How FairSIM works
Three steps between you and the internet abroad. Nothing to pick up at the airport.
Pick a destination and a plan
Choose the country or region and the data you need. The price you see is the price you pay.
Tap install
On iPhone (iOS 17.4+) the eSIM installs in one tap, no QR code. Do it at home while you still have Wi-Fi.
Land and connect
Turn on data roaming for the FairSIM line when you arrive. Your plan starts when it first connects.
Connectivity tips for Montserrat
Install the eSIM before you leave home or while you are on Wi-Fi in Antigua. Validity typically starts when the line first connects to a network in Montserrat.
You need a local visitor's driving permit to drive here. It is issued on arrival at the airport or ferry terminal, or at the police station, for a small fee, and you drive on the left.
Do not enter the Exclusion Zone on your own. Access to the restricted zones is controlled and the accessible parts are visited with a licensed guide; check the Montserrat Volcano Observatory hazard level for the week.
Jack Boy Hill and Garibaldi Hill give the legal, safe views over buried Plymouth, and both have signal for photos.
Carry cash. EC dollars and US dollars are both fine, but cards are not accepted everywhere and ATMs are few.
Download offline maps for the Centre Hills and the Oriole Walkway; the ghauts swallow signal.
Confirm ferry and flight times the day before by phone or WhatsApp, and again on the morning. Weather changes schedules.
Keep your home SIM in the phone with its data roaming switched off, so bank one-time codes still arrive while the eSIM carries the data.
Can you rely on free Wi-Fi?
Most villas, guesthouses and the better restaurants have Wi-Fi, usually FLOW fixed broadband, and in the north it is generally decent for browsing and video calls. It is not universal and it is not always stable: heavy rain, power cuts and the occasional outage take the connection with them, and public hotspots outside accommodation are few. Treat Wi-Fi as the comfortable option at the house and your eSIM as the one that works at the viewpoint, the beach and the ferry dock.
Local SIM card or eSIM in Montserrat?
FLOW and Digicel both sell prepaid SIMs on the island, from their offices and dealers in the Brades and Sweeney's area. You bring your passport, you pay in EC dollars or US dollars, and you top up at shops and petrol stations. Rates are reasonable and coverage is the same as anything else on those towers. The friction is timing: Montserrat runs on small-island hours, shops close early, Sunday is quiet, and the airport at Gerald's is a single small terminal with no SIM counter waiting for you. If you land Saturday afternoon for a three-night stay, half your trip can pass before you are connected.
A FairSIM eSIM avoids that. You install it over Wi-Fi before you fly, usually while you are still in Antigua or at home, then switch on the line and data roaming when you land and it attaches to Digicel or FLOW. Same towers, no passport registration, no shop visit, and your home number stays in the phone for bank codes and airline messages. A local SIM still makes sense if you need a Montserrat phone number for a long stay or a lot of local calling; for a week or two of maps, WhatsApp and hotspot, the eSIM is simply less hassle.
Montserrat eSIM questions
Does eSIM work in Montserrat?
Yes. An unlocked eSIM-capable phone connects to Digicel or FLOW with a travel eSIM. On iPhone that means XS, XR or newer; most recent Android flagships and Pixels support eSIM too.
Which network will my Montserrat eSIM use?
Digicel or FLOW, the two operators on the island. The app shows which network a plan uses before you buy.
Is there 5G in Montserrat?
No. Both Digicel and FLOW run 4G LTE here, with 3G and 2G fallback. Any 5G icon you see is your phone showing a network from somewhere else.
Will I have signal at the volcano viewpoints?
Jack Boy Hill, Garibaldi Hill and the Montserrat Volcano Observatory area are in the covered north and normally have 4G. Deep ghauts and inner Centre Hills trails are where you lose it, so download maps first.
Can I use Personal Hotspot in Montserrat?
Yes. FairSIM plans support Personal Hotspot with no separate cap, which is useful when villa broadband goes down with the power.
Do WhatsApp calls work in Montserrat?
Yes. There is no restriction on internet calling here, so WhatsApp, FaceTime and Messenger calls work over the eSIM and over Wi-Fi, subject to the connection quality.
Should I buy a Montserrat plan or an Antigua plan for a day trip?
They are separate countries for roaming. If you are based in Antigua and crossing for a day, a Montserrat plan keeps you connected on the island; if you need both, buy both from the app, since your Antigua plan will not cover Montserrat.
How much data do I need in Montserrat?
A day trip uses well under 1 GB. A long weekend of maps, messaging and photos is around 3 to 5 GB. A week with some streaming and hotspot use is closer to 10 GB, and a working month is best on a large or unlimited plan.
Local SIM or travel eSIM for Montserrat?
A local Digicel or FLOW SIM is cheap but means finding a shop in Brades during opening hours with your passport. A travel eSIM is installed before you fly, roams on the same two networks, and keeps your home number active for codes.
What is an eSIM?
A SIM card built into your phone. Instead of a plastic chip, you download a profile. Every iPhone since the XS has one next to the physical SIM slot, so your home number stays put while FairSIM supplies the data.
Is my phone compatible?
FairSIM works with eSIM-compatible, carrier-unlocked iPhones: the XS, XR and everything newer, on iOS 17.4 or later for the one-tap install with no QR code. iPhones bought in mainland China do not support eSIM at all, even when unlocked. Not sure yours is unlocked? Check Settings, General, About, Carrier Lock, or ask your carrier. The full list is on the How it works page.
When should I install my eSIM?
Before you travel, while you still have Wi-Fi. Installing does not start your plan; the validity typically starts when the eSIM first connects to a network at your destination.
Do FairSIM eSIMs come with a phone number?
No. FairSIM eSIMs are data-only by design, which keeps costs low. For calls and texts, your physical SIM stays active so you keep your existing number, and WhatsApp, FaceTime and iMessage work over data.
