FLOW across both islands
Your eSIM connects to FLOW on 4G, covering St Kitts and Nevis on one plan. Basseterre, Frigate Bay, the southeast peninsula and the coastal ring road are all well covered, as is Charlestown and most of Nevis.
The central mountains on both islands — Mount Liamuiga on St Kitts, Nevis Peak — lose signal as you climb into the rainforest.
The ferry, the railway and getting between
The two islands are separated by a two-mile channel called The Narrows, and the ferry between Basseterre and Charlestown takes about 45 minutes. Signal holds for most of it given how short the crossing is.
The St Kitts Scenic Railway, built to carry sugar cane and now carrying tourists around the island's edge, has coverage for nearly its whole route — it follows the coast where the network is.
How much data
1 GB at £9.99 covers a week for most visitors, with resort Wi-Fi handling the rest. If you're splitting time across both islands and moving about a lot, 3 GB gives more headroom.
Good to know
Questions, answered
Does one plan cover both St Kitts and Nevis?+
Yes, both islands are on the same FLOW network and the same plan. The ferry between them is short enough to hold signal for most of the crossing.
Is there coverage climbing Nevis Peak or Mount Liamuiga?+
It drops off as you climb into the rainforest. Both are guided climbs and steeper than they look — your guide matters more than your phone up there.
How do I install it?+
After checkout we email your eSIM and a QR code. Scan it in your phone's settings, switch the line on, and you're ready — do it before you fly and it activates when you land.
Will it work on my phone?+
Most phones from the last few years support eSIM (iPhone XS and newer, recent Samsung/Pixel). Check your phone in Settings, or use our compatibility checker.
When does my plan start?+
Validity counts from first connection in the destination, not from purchase — so you can buy and install early without wasting days.
Can I keep using my normal number?+
Yes. The eSIM is data-only and runs alongside your usual SIM, so calls and texts on your main number still work.
