Montserrat eSIM: Stay Connected on the Emerald Isle

Montserrat is reached by a short flight from Antigua to John A. Osborne Airport at Gerald's in the north of the island, or by ferry from Antigua into Little Bay when sailings are running. If your HelloSIM eSIM is installed before you set off, it connects to the island's network when you arrive.

Why use an eSIM in Montserrat

• Connections run via Antigua, so having data during the transfer lets you check flight or ferry times and message whoever is meeting you.
• Arranging a taxi or a hiking guide is easier when you can contact them directly from your own line.
• Trails in the Centre Hills are best tackled with a downloaded map and someone who knows your route.
• Roaming on your home plan can add a daily fee, so have a look at your tariff before you travel.
• WhatsApp stays on your normal number, and your own SIM still takes calls and texts.

Montserrat is small, green and quiet, and it is often called the Emerald Isle of the Caribbean for its Irish heritage and lush hills. Life on the island is centred on the north, and parts of the south are restricted, so plan your sightseeing around the areas that are open to visitors.

Networks and coverage

The HelloSIM eSIM connects to Flow (Cable & Wireless) on Montserrat, using its 4G network; you'll be on 4G/LTE, as 5G isn't offered on this plan.

Signal is usually reliable in the inhabited north, including Brades, Little Bay, the area around the airport at Gerald's and west-side villages such as Salem and Woodlands.

Reception can be weak on forest trails in the Centre Hills, at secluded beaches such as Rendezvous Bay, which you reach on foot or by boat, and out at sea during the ferry crossing.

How to get connected

1. 1Confirm your handset supports eSIM and is unlocked, then buy the Montserrat plan. We email the QR code straight away, and it's also stored in your HelloSIM account.
2. 2Scan the code on Wi-Fi at home, well before your connection in Antigua: on iPhone through Settings → Mobile → Add eSIM, on Android through Settings → Network & internet or Connections → SIM manager → Add eSIM (exact names depend on the manufacturer).
3. 3When you reach Montserrat, switch on the HelloSIM line, choose it for mobile data and allow Data Roaming on that line. It must be on for the eSIM to connect, and it won't cost extra, since the data is prepaid.
4. 4Turn off data roaming for your home SIM, which stops your regular carrier from charging roaming fees.

How much data do you need

• Light — maps, messages and keeping an eye on flight times: around 1 GB a week.
• Medium — sharing views from the hills, social apps and everyday browsing: 3–5 GB a week.
• Heavy — video calls, streaming and remote work: 10 GB or more a week.

Guesthouses and villas generally offer Wi-Fi, but it can be basic, so it's sensible to have your own data as well.

Good to know

• Currency: Eastern Caribbean dollar (XCD), shared with several neighbouring islands
• Seat of government: Brades, in the north
• Language: English is spoken throughout
• Time zone: UTC−4, the same all year
• Don't miss: the Montserrat Volcano Observatory, Rendezvous Bay and the St Patrick's Day celebrations in March

Travel tips for staying connected in Montserrat

• Before a hike in the Centre Hills, download an offline map and tell your guesthouse which trail you're taking.
• Parts of the south are restricted, so follow local signs and guidance rather than whatever route a navigation app suggests.
• On the ferry from Antigua, keep data roaming off on your home line; your phone may roam on Antigua's networks during the crossing, and your carrier could bill you for it.
• Planning the walk or boat trip to Rendezvous Bay? Save what you need offline first, as you may have no signal there.
• If you run short of data, top up the existing eSIM through your HelloSIM account; there's no new code to scan.

Spending a few days in Antigua either side of Montserrat? The Caribbean regional plan can put several islands on one eSIM; check that each island on your route, Antigua included, is listed before you buy.
