A 102 km² British Overseas Territory with an active volcano
Montserrat is a small Caribbean island in the Leewards — about 16 km long, 11 km wide, with a population of around 5,000 people. Most of the original capital, Plymouth, was buried under volcanic ash from the Soufrière Hills eruptions starting in 1995, and the southern half of the island is still an exclusion zone where neither residents nor visitors are permitted. The functioning country lives in the northern half: government offices in Brades, the new Little Bay port and capital area, John A. Osborne airport (MNI). The cellular network covers the populated north workably; the exclusion zone has signal pulled from the north but is off-limits anyway.
Roamzy charges $11.78 per gigabyte in Montserrat. That's $0.0115 per megabyte, billed in real time on Montserratian networks. No subscription, no expiry, no minimum bundle. One per-MB rate across 193 countries.
How much does Roamzy cost on a typical visit?
Cellular use is light because the country is small and most travelers are either on a day-trip from Antigua or staying at a property with Wi-Fi: maps in the north, the WhatsApp to a guide for the volcano-observatory tour, voice notes home, the rare bank-app push. Plan on 0.2–0.4 GB/day on cellular:
| Trip pattern | Roamzy ($11.78/GB) | Tourist roaming pass | Cruise-ship Wi-Fi |
|---|---|---|---|
| 1-day boat trip from Antigua (~0.3 GB) | $3.53 | — | $20–35 |
| 3 days on-island (~1 GB) | $11.78 | $25–60 | — |
| 1 week (~2.5 GB) | $29.44 | $50–120 | — |
Competitor prices in columns 3 and 4 are 2025 ranges based on typical offerings; exact figures depend on your home carrier, hotel, or cruise line. Roamzy's rate in column 2 is our actual published rate from the pricing page.
Day-trippers from Antigua benefit most: the ferry doesn't sell SIMs, the eSIM is already attached when you walk off the boat at Little Bay, and you pay for the half-gigabyte you actually used on the ground.
What works across the northern half
- Brades, Little Bay, the government area — 4G/LTE; signal across the populated north
- Salem, Cudjoe Head, Davy Hill — workable LTE in the residential settlements
- John A. Osborne airport (MNI) and the access road — strong LTE
- Rendezvous Bay, Little Bay beach — fine on the developed beach, weaker behind the headlands
- Volcano Observatory and the exclusion-zone viewpoints — 4G at the observatory; the exclusion zone itself you don't enter, the signal radiates from the north anyway
- Centre Hills nature reserve, hiking trails — workable on the lower trails, weaker on the ridges
How do I install my Roamzy eSIM?
| Plug type | Voltage | Frequency | iOS | Android |
|---|---|---|---|---|
| Type A, B | 230 V | 60 Hz | iPhone XS+ | Pixel 3+, Galaxy S20+ |
- Sign in to Roamzy via Telegram or Google
- Top up with a minimum of 20 USDT — stablecoins, no cards, no banks, no FX surcharges
- The QR code appears in the dashboard once payment confirms
- Settings → Cellular → Add eSIM → scan QR
- The counter starts when you land at MNI or step off the ferry at Little Bay
Outlets in Montserrat are unusual — Type A/B plugs but at 230 V and 60 Hz, a hybrid of US and UK conventions. Setup edge cases are in the FAQ. The dashboard handles top-ups in USDT.
What are Roamzy's honest limitations?
- No welcome promo that flips on the second top-up. Top-up #1 and top-up #20 cost the same per megabyte.
- No fine-print throttling. One rate, full speed — first GB and the tenth both cost $0.0115/MB.
- No auto-renewal. Balance runs out, the eSIM stops.
It's not a marketing gimmick — it's an engineering decision born from indifference to gimmicks.
What if my route continues across the Lesser Antilles?
- Anguilla — north up the Leewards, separate country rate
- Saint Kitts and Nevis — close pairing in any Leewards itinerary
