Will I have data at Sardinia's remote beaches?

Often not - many famous coves lie at the end of unmarked dirt tracks with no coverage, so pin the location and any paid-access booking while you still have signal in the nearest town.

Is a hire car necessary, and will navigation work?

A car is essential as public transport is sparse, and the eSIM handles navigation well on main roads; just download offline maps for the mountain interior where signal drops between villages.

Good to know in Sardinia

Sardinia's best beaches sit at the end of unmarked dirt tracks with no signal, so pin the exact cove and any daily-access booking - some now require pre-paid permits - while you still have data in town.

Best time to visit Sardinia

June and September give warm seas and quieter beaches; July and August are glorious but expensive, crowded and hard to book.

Two simple ways to buy

Sardinia eSIM plans: unlimited, or by the GB.

Every Sardinia eSIM from My Holiday SIM is one of two straightforward types. Pick whichever fits how you travel in Sardinia — 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 Sardinia?

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

Sardinia eSIM: your local data guide.

Sardinia is a beach-and-nature island: the turquoise coves of the Costa Smeralda, Catalan-flavoured Alghero, the granite islets of La Maddalena and wild interior mountains around Gennargentu. A Sardinia eSIM keeps beach-access maps, boat-tour bookings and long coastal-drive navigation live, which matters when villages sit far apart and public transport is thin.

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

Install the QR at home, then switch the eSIM on as you taxi in — you're online before you reach the arrivals hall.

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

Across the region

Where you'll lean on data in Sardinia.

Cagliari

Cagliari's centre and Poetto beach have solid 4G and 5G for maps, ferry check-ins and booking a seafood dinner in the Marina district.

Costa Smeralda

Around Porto Cervo and the Costa Smeralda coverage is good in the resorts but drops on the approach roads to hidden coves.

Alghero

In Alghero the old town holds reliable signal for navigating the sea walls and booking Neptune's Grotto boat trips.

La Maddalena Archipelago

On the La Maddalena islands signal fades on remote beaches, so screenshot your boat schedule before leaving Palau.

The practical bit

Getting around Sardinia on your eSIM.

Apps you'll want online in Sardinia

ARST— Sardinia's regional bus network connecting Cagliari, Alghero and coastal towns.
appTaxi— Book licensed taxis in Cagliari and Sassari.
Trenitalia— Limited regional rail linking Cagliari, Oristano and Sassari.
Ferryhopper— Compare and book ferries to Sardinia and its offshore islands.

How long to stay in Sardinia

A week to ten days suits Sardinia, with a hire car essential to link the northern Costa Smeralda, Alghero and the southern Cagliari coast.

How much data for Sardinia

A balanced 3-5 GB covers a week of coastal navigation, beach-finding and photos; light beach holidays staying put may need only 1-2 GB.

Coverage in Sardinia

The national Italy eSIM roams on TIM, Vodafone and WindTre; towns and major resorts get strong signal, but the mountainous Gennargentu interior and remote beaches genuinely lose coverage.

Sardinia eSIM questions, answered.

Yes - it's the national Italy plan, working from Cagliari to the Costa Smeralda, Alghero and La Maddalena, though remote beaches and the mountainous interior genuinely have weaker or no signal.
