FLOW 4G is the only network on Montserrat

FLOW is the only mobile network on Montserrat, so every HelloRoam Montserrat plan attaches to it and nothing else. The island's coverage is limited to the northern inhabited zone after the southern half entered a permanent exclusion zone following Soufrière Hills volcano activity. Little Bay (the de facto new capital in development), Salem, Brades, and St.

John's in the north have 4G coverage. The Gerald's Airport area and ferry terminal at Little Bay have reliable signal. Coverage quality is adequate for navigation and messaging on a smaller Eastern Caribbean island network.

通信範囲の分析

FLOW 4G covers the northern inhabited zone: Little Bay harbor and ferry terminal, Brades (the current administrative center), Salem, Cudjoe Head, and Gerald's Airport. The exclusion zone boundary viewing area near Old Towne has intermittent signal. Montserrat Volcano Observatory has workable coverage.

Centre Hills trail access points have signal at trailheads; remote forest interior drops to 3G. The west coast road from Little Bay to Salem has consistent 4G. The abandoned south including Plymouth remains in the exclusion zone with no public access.

開通方法

Montserrat has no commercial jet airport. Most visitors arrive by ferry from Antigua or by small charter aircraft to Gerald's Airport. Install your eSIM before leaving Antigua or your origin country, then turn the line on when you arrive.

FLOW registers automatically at Little Bay ferry terminal and at Gerald's Airport. No SIM counter exists on the island; buying a local SIM means visiting a FLOW shop in Brades, which makes an eSIM the practical option. iPhone XS or newer, Pixel 3a or newer, and Galaxy S20 or newer support eSIM.

データ通信の活用のコツ

Budget 200-400 MB per day for Google Maps around Montserrat's northern road network, WhatsApp with tour guides for volcano observation tours, and posting from the exclusion zone viewpoint with Plymouth in the background. Download offline maps of Montserrat before arrival, because FLOW's smaller network makes live map requests slower. A week's visit typically uses 2-4 GB, which the $40.80 5 GB plan covers.

A 2 GB per day plan at $18 fits heavy days such as a Centre Hills hike or a helicopter overflight of the volcano.

MontserratのeSIMプラン料金

Montserrat eSIM plans start at $10.98 for 1 GB over 7 days on FLOW 4G. A 3 GB plan costs $26.10 and 5 GB costs $40.80. Ten GB costs $74.66, which works out to $7.47 per GB.

Twenty GB costs $164.45. A 2 GB per day plan costs $18. Island pricing runs high here: HelloRoam's median across 185 destinations is $2.20 per GB.

Bottom line: a week of volcano tours and Centre Hills hiking costs $40.80 at 5 GB on FLOW 4G, and no SIM counter exists at the ferry terminal or the airport to undercut it.
