Is there signal on the South West Coast Path?

In and near towns, yes, but the cliff sections between villages regularly drop out. Download OS or coast-path maps and tide times before setting off on longer walks.

Will data reach the Isles of Scilly?

The eSIM works on the islands where masts allow, but coverage is thinner than the mainland and can vary between St Mary's and the off-islands, so don't rely on it for everything.

Good to know in Cornwall

Cornwall's single-track lanes and summer traffic can be brutal; use live data for real-time routing around the A30 jams, but download surf and tide apps as coast-path coverage is unreliable.

Best time to visit Cornwall

Late May to September delivers the warmest sea and best surf-and-beach weather; expect heavy crowds and booked-out roads in the July and August school holidays.

Two simple ways to buy

Cornwall eSIM plans: unlimited, or by the GB.

Every Cornwall eSIM from My Holiday SIM is one of two straightforward types. Pick whichever fits how you travel in Cornwall — you can always top up or switch on your next trip.

Traveller streaming and browsing freely on an unlimited-data travel eSIM

Unlimited plans

High-speed data, nothing to count

Priced per day — the longer you stay, the better the daily rate. Ideal for streaming, hotspot and longer trips where you'd rather not watch a data meter. A fair-use policy keeps speeds fast for everyone; see each plan for the detail.

Best for streaming, video calls & hotspot
Great for longer or open-ended trips
One price per day — no GB anxiety

By-the-GB plans

3GB10GB20GB

A set bundle, brilliant value

A fixed data allowance (say 3 GB or 10 GB) valid for your travel days. The best-value pick for lighter trips built around maps, messaging and a bit of browsing. Running low? Top up in a couple of taps — nothing to reinstall.

How much data do you need in Cornwall?

A rough, honest guide to sizing your Cornwall eSIM so you're not guessing. Most travellers in Cornwall are comfortable on 3–5 GB a week — heavy streamers just go Unlimited.

Cornwall eSIM: your local data guide.

Cornwall is England's surf-and-sea corner: the galleries of St Ives, the beaches of Newquay and Fistral, the Eden Project and the long South West Coast Path out to Land's End. A Cornwall eSIM keeps your surf forecasts, tide times and coast-path maps live, which matters on cliff walks and coves where signal comes and goes.

One eSIM for Cornwall and all of United Kingdom. It's the national United Kingdom eSIM — from $2.15/day with unlimited data, working the same in Cornwall as it does the moment you leave it.

Cornwall eSIM from $2.15/day — the whole bill, agreed before you fly.

Across the region

Where you'll lean on data in Cornwall.

Newquay

The surf capital has solid coverage for booking lessons, checking Fistral swell and hotspotting from cafés.

St Ives

Reliable data through the town and harbour, though the coast path out towards Zennor has weaker patches.

Land's End

Signal reaches the main site but dips along the remote cliff paths of the Penwith peninsula.

Lizard Peninsula

Villages are covered, but Britain's southern tip has stretches of coast path with little or no signal.

The practical bit

Getting around Cornwall on your eSIM.

Apps you'll want online in Cornwall

Surfline— Live surf and swell forecasts for Fistral and Cornwall's beaches.
Trainline— Great Western and branch-line rail times to Penzance and St Ives.
Google Maps— Live routing around A30 jams and Cornwall's narrow summer lanes.
First Bus— Cornwall bus times and tickets for coastal and town routes.

How long to stay in Cornwall

A Cornwall break usually lasts four days to a week, enough to base near a surf beach and day-trip to St Ives, the Eden Project and Land's End.

How much data for Cornwall

Light-to-balanced 2-4 GB covers a week of maps, surf and tide apps; go higher if you'll stream or hotspot from a cottage during the frequent rainy spells.

Coverage in Cornwall

Towns like Truro, Newquay and St Ives have good 4G and 5G, and main roads stay connected, but signal genuinely thins on the cliff-top coast path, remote coves and out to the Isles of Scilly.

Cornwall eSIM questions, answered.

No. Cornwall is part of England, so the national United Kingdom plan covers it, roaming onto networks like EE, O2, Vodafone and Three. The same data works whether you're in Truro or on a beach.
