The short answer
Six travel eSIMs get most of the traffic for this search, and all six can put you online in Montserrat, some with a plan for the island and some with a Caribbean or world plan. I priced all six on the same day, for a few days over from Antigua, a week or two of hiking and volcano tours, and a month, and read the fine print on unlimited. Here is where each one wins, as I read it.
Unlimited data at full speed for 2 weeks at $48.99 or 30 days at $93.99, nothing renews. Holafly asks $69.50 for 15 days, and Ubigi $108 for a month of 60 GB at full speed.
A Montserrat plan on FLOW: 3 days at $19.90, 7 days at $37.90. No daily cap stated for your own phone; sharing limited to 1 GB a day.
Its Island Hopper Caribbean plan: 3 days at $19.50, 3 GB a day at full speed, then 1 Mbps. Its own Montserrat plan, on Digicel, sells buckets up to 5 GB.
10 GB for 30 days at $34 and 20 GB at $49, on a Montserrat plan on FLOW. No unlimited plan.
Prices read on 31 October 2026: Airalo, Holafly, Saily, Nomad, Ubigi on their own sites or listings, Ringo Light from its catalogue. All in US dollars unless stated. Treat every number as a snapshot.

What to do in Montserrat, and what your phone needs for it
Seven places most first trips include, from the volcano and the buried capital in the south to Little Bay and the green north where everyone lives, with the one thing your data does for you at each. Signal is good in the north and thinner on the trails and near the exclusion zone.
If you want unlimited for two weeks or a month: Ringo Light
Most people who come to Montserrat stay a few days to two weeks, for the volcano, the hikes in the Centre Hills and the quiet. Data is what you use for maps, WhatsApp with guides and drivers, the ferry and flight messages, and a film in the evening. For about two weeks of unlimited, Holafly asks $69.50 for 15 days, Ubigi $75 for 30 GB at full speed on its Caribbean plan, and Airalo $96 on its Discover global plan. For a month, $108 to $159. Saily and Nomad sell no unlimited here. Ringo Light charges $48.99 for 2 weeks and $93.99 for 30 days, nothing renews.
I read what unlimited means before I pick a plan. Airalo gives 3 GB a day at full speed, then 1 Mbps. Ubigi gives 20 GB for 7 days, 30 GB for 15 days or 60 GB for the month, then 2 Mbps. Holafly states no daily cap for your own phone and limits sharing to 1 GB a day. Ringo Light is unlimited data at full speed for the whole trip.
For a short trip, Ringo Light sells no 3-day plan. Airalo's Island Hopper sells 3 days of unlimited at $19.50, Holafly 3 days at $19.90 and a week at $37.90, $1.09 less than Ringo's 7 days at $38.99. For a week on the island I would take Holafly, though Ringo's 7 days costs less than Ubigi's $44 or Airalo's $45. For 3 days, Airalo at $19.50 is the cheaper trip.
Arriving through Antigua, and the zone around the volcano
There is no long-haul flight to Montserrat. Almost everyone comes through V. C. Bird airport on Antigua, then takes a short flight on a small propeller plane to John A. Osborne airport in the north, or the ferry from St John's to Little Bay on the days it sails. A plan for Montserrat alone, Ringo's or Holafly's, does nothing on Antigua. It connects once your phone finds a Montserrat network and stops again on the way back. For the landing day, I would keep something for Antigua: airport Wi-Fi, your home plan, or a second plan. Airalo's Discover plan is global. Ringo's Caribbean trip covers neither Montserrat nor Antigua; for Antigua, read /blog/best-esim-for-antigua-and-barbuda.
The southern part of the island, around the Soufrière Hills volcano and the old capital Plymouth, is an exclusion zone. The Montserrat Volcano Observatory sets the hazard level and which zones are open, and the buried town can only be visited on a tour with an approved guide. Everyone lives in the north, and that is where the networks are strongest.
Two networks, and where the signal thins
Montserrat has two mobile networks, FLOW and Digicel. Both cover the inhabited north, around Brades, Little Bay and Salem, and the airport. I read Holafly's own page, and it warns that coverage weakens in mountainous and forested areas, on hiking routes, on some boat trips, and names parts of the Centre Hills, the Silver Hills and the trails near Rendezvous Bay. Holafly and Nomad ride FLOW, Airalo's Montserrat plan and Ubigi Digicel; Saily does not name its network.
The Eastern Caribbean dollar is the local currency and US dollars are widely taken. There is no ride hailing app on the island, so taxis and guides are booked by phone.
If you want a data bucket: Nomad or Ubigi
- Nomad, $34 for 10 GB. A Montserrat plan on FLOW, and the cheapest 20 GB for 30 days at $49 that does not renew.
- Ubigi, $34 for 10 GB. On its Caribbean plan, on Digicel. Its World plan sells 20 GB a month for $44, but it renews every month until you stop it.
- Saily, $35.99 for 10 GB. On its Montserrat plan, which stops at 10 GB. Its listing is from May; saily.com would not load at all.
- Airalo, $57 for 10 GB. Only on its Discover global plan, valid 180 days. Its own Montserrat plan stops at 5 GB for 30 days at $32.50, and starts at 1 GB for 3 days at $8.
- ✓Ringo Light, no buckets. Its 2 weeks is unlimited for $48.99 and its 30 days unlimited for $93.99. For a fixed amount of data, Nomad, Ubigi and Saily are all cheaper in Montserrat. I would buy Ringo Light for unlimited, not for a bucket. I would rather you read that here than at checkout.
What Ringo Light is
Ringo Light is Ringo's own data eSIM, sold to fund the full Ringo, one plan that works everywhere with your own number ported onto it. I write for Ringo, and I say so before I recommend it. For Montserrat it sells three trips, all unlimited data at full speed with no speed cap: 7 days at $38.99, 2 weeks at $48.99 and 30 days at $93.99. Nothing renews. The eSIM arrives by email in seconds and installs in one scan, no app. It works in Montserrat only, not on Antigua.
The card to buy it is further up this page, just after the side-by-side table.
